(3) The isoelectric point, pI or pH(I), is the pH value where the enzyme molecule is neutral, i.e. the sum of electrostatic charges (net electrostatic charge, =NEC, or net charge) of the molecule is equal to zero. Positive or negative nature of the individual electrostatic charges must be taken into account. The isoelectric point may be calculated by using equilibrium considerations using pKa values for the various charged residues in the enzyme in question and then by iteration find the pH value where the NEC of the enzyme molecule is equal to zero.
(4) The net charge of the molecule is affected by the pH of its surrounding environment and can become larger or smaller due to the gain or loss, respectively, of protons (H.sup.+).
(5) The pK.sub.a values for the charged residues are dependent on their environment and are consequently subject to variation. However, specific approximate pK.sub.a values may be allocated to the charged residues independently of the actual value. The pI of an enzyme molecule may also be determined experimentally by isoelectric focusing or by titrating a solution containing the enzyme. Various pK.sub.a values for the charged residues may be determined experimentally by titration.
(6) It has previously been shown in WO91/000345 (Novozymes A/S) that changes in the pI of a protease by making specific substitutions to produce a protease variants having altered overall pI or electrostatic charge influences the wash performance at various pH values.
(7) An embodiment of the invention relates to protease variants, wherein the net electrostatic charge has been changed in comparison to the parent protease at the same pH, and in which proteases there have, relative to said parent protease, either more positively charged amino acid residue(s) and/or fewer negatively charged amino acid residue(s), wherein protease variants comprising one or more of the alterations selected from the list consisting of: V2H, S4K, S4H, T5K, Q6K, N16K, N16H, D17N, Q18K, Q18H, S19K, T24K, T24H, T24R, S27K, Y39R, S41K, L43H, G47K, E50Q, E50T, E50L, Q57K, S58K, N59K, D63N, G64H, S65K, T67K, Q70H, G85R, G85H, S86K, N87K, Y92R, Q97K, D108N, D108S, D108A, N109K, S111K, S111R, G112R, S114K, D116S, D116A, A118R, A118K, D126G, D126W, D126K, E127Q, E127K, E127L, E127S, S129K, R130K, T131K, T131H, G132H, G142K, G142R, S143K, S143H, S144K, D147N, D147S, D147*, D147Q, D147H, D147W, S148K, L149K, D155H, Y156R, Y156H, G159H, G174R, G174H, T177K, L184H, V185K, N186K, N186R, E194*, E194S, E194K, E194Q, N195H, N195K, V196H, Q197K, Q197H, Q197R, Q198K, N199K, G200H, D206N, D206H, F207H, N212K, A214R, A214K, T215K, D218N, D218H, D218R, Y219R, Y219H, I220K, I220H, Q222K, D225N, A233R, S234K, E236C, T241K, N245K, T246K, I247K, S248K, I264R, A267H, N268K, N268H, T269K, T269H, S270K, S272K, S274K, T278K, T278H, E279Q, E279H, V286H, V286K, Y287R, Y287H, D288N, D288K, I293R, I293K, T297K, D299R and K311R wherein the positions corresponding to positions of SEQ ID NO 3.
(8) For those of the amino acids above having a negatively charged amino acid at the relevant pH replacing this amino acid with any neutral or positively charged amino acid at the same pH will result in an increased charge at that residue. According to one embodiment, the sum of amino acid charges of protease variants of the invention is greater than the sum of amino acid charges of the parent protease. Thus the protease variants of the invention have a net charge greater than that of the parent protease.
(9) Changing the net charge of SEQ ID NO 3, SEQ ID NO 4 or SEQ ID NO 5 to become larger in model B detergent (pH 7.8) increases the wash performance of the molecule as measured in Example 2 in Materials and Methods herein. The effect may be demonstrated by comparing with a set of variants engineered to become more negative under the same conditions.

(18) The variants may further comprise one or more additional alterations at one or more (e.g., several) other positions. The amino acid changes may be of a minor nature, that is conservative amino acid substitutions or insertions that do not significantly affect the folding and/or activity of the protein; small deletions, typically of 1-5 amino acids; small amino- or carboxyl-terminal extensions, such as an amino-terminal methionine residue; a small linker peptide of up to 20-25 residues, located at the amino- or carboxyl terminal; or a small extension that facilitates purification by changing net charge or another function, such as a poly-histidine tract, an antigenic epitope or a binding domain.
(19) Examples of conservative substitutions are within the groups of basic amino acids (arginine, lysine and histidine), acidic amino acids (glutamic acid and aspartic acid), polar amino acids (glutamine and asparagine), hydrophobic amino acids (leucine, isoleucine and valine), aromatic amino acids (phenylalanine, tryptophan and tyrosine), and small amino acids (glycine, alanine, serine, threonine and methionine). Amino acid substitutions that do not generally alter specific activity are known in the art and are described, for example, by H. Neurath and R. L. Hill, 1979, In, The Proteins, Academic Press, New York. Common substitutions are Ala/Ser, Val/Ile, Asp/Glu, Asn/Gln, Thr/Ser, Ala/Gly, Ala/Thr, Ser/Asn, Ala/Val, Ser/Gly, Tyr/Phe, Ala/Pro, Lys/Arg, Asp/Asn, Glu/Gln, Leu/Ile, Leu/Val, Ala/Glu, and Asp/Gly.
(20) Alternatively, the amino acid changes are of such a nature that the physico-chemical properties of the polypeptides are altered. For example, amino acid changes may improve the thermal stability of the polypeptide, alter the substrate specificity, change the pH optimum, and the like.
(21) Essential amino acids in a polypeptide can be identified according to procedures known in the art, such as site-directed mutagenesis or alanine-scanning mutagenesis (Cunningham and Wells, 1989, Science 244: 1081-1085). In the latter technique, single alanine mutations are introduced at every residue in the molecule, and the resultant mutant molecules are tested for protease activity to identify amino acid residues that are critical to the activity of the molecule. See also, Hilton et al., 1996, J. Biol. Chem. 271: 4699-4708. The active site of the enzyme or other biological interaction can also be determined by physical analysis of structure, as determined by such techniques as nuclear magnetic resonance, crystallography, electron diffraction, or photoaffinity labeling, in conjunction with mutation of putative contact site amino acids. See, for example, de Vos et al., 1992, Science 255: 306-312; Smith et al., 1992, J. Mol. Biol. 224: 899-904; Wlodaver et al., 1992, FEBS Lett. 309: 59-64. The identity of essential amino acids can also be inferred from an alignment with a related polypeptide. For the TY-145 protease (SEQ ID NO: 3) the catalytic triad comprising the amino acids D35, H72 and S251 is essential for protease activity of the enzyme.
(22) In an embodiment, the variant has improved catalytic activity compared to the parent enzyme.
(23) The homology between two amino acid sequences is in this context described by the parameter “identity” for purposes of the present invention, the degree of identity between two amino acid sequences is determined using the Needleman-Wunsch algorithm as described above. The output from the routine is besides the amino acid alignment the calculation of the “Percent Identity” between the two sequences.
(24) Based on this description it is routine for a person skilled in the art to identify suitable homologous proteases, which can be modified according to the invention.
(25) Substantially homologous parent protease variants may have one or more (several) amino acid substitutions, deletions and/or insertions, in the present context the term “one or more” is used interchangeably with the term “several”. These changes are preferably of a minor nature, that is conservative amino acid substitutions as described above and other substitutions that do not significantly affect the three-dimensional folding or activity of the protein or polypeptide; small deletions, typically of one to about 30 amino acids; and small amino- or carboxyl-terminal extensions, such as an amino-terminal methionine residue, a small linker peptide of up to about 20-25 residues, or a small extension that facilitates purification (an affinity tag), such as a poly-histidine tract, or protein A (Nilsson et al., 1985, EMBO J. 4: 1075; Nilsson et al., 1991, Methods Enzymol. 198: 3. See, also, in general, Ford et al., 1991, Protein Expression and Purification 2: 95-107.
(26) Although the changes described above preferably are of a minor nature, such changes may also be of a substantive nature such as fusion of larger polypeptides of up to 300 amino acids or more both as amino- or carboxyl-terminal extensions.
(27) The parent protease may comprise or consist of the amino acid sequence of SEQ ID NO: 3 or an allelic variant thereof; or a fragment thereof having protease activity. In one aspect, the parent protease comprises or consists of the amino acid sequence of SEQ ID NO: 3.
(28) The parent protease may be (a) a polypeptide having at least 60% sequence identity to polypeptide of SEQ ID NO: 3; (b) a polypeptide encoded by a polynucleotide that hybridizes under medium or high stringency conditions with (i) the mature polypeptide coding sequence of SEQ ID NO: 1, (ii) a sequence encoding the mature polypeptide of SEQ ID NO: 2, or (iii) the full-length complement of (i) or (ii); or (c) a polypeptide encoded by a polynucleotide having at least 60% sequence identity to the mature polypeptide coding sequence of SEQ ID NO: 1.
(29) In an aspect, the parent protease has a sequence identity to the polypeptide with SEQ ID NO: 3 of at least 60%, at least 61%, at least 62%, at least 63%, at least 64%, at least 65%, at least 66%, at least 67%, at least 68%, at least 69%, at least 70%, at least 71%, at least 72%, at least 73%, at least 74%, at least 75%, at least 76%, at least 77%, at least 78%, at least 79%, at least 80%, at least 81%, at least 82%, at least 83%, at least 84%, at least 85%, at least 86%, at least 87%, at least 88%, at least 89%, at least 90%, at least 91%, at least 92%, at least 93%, at least 94%, at least 95%, at least 96%, at least 97%, at least 98% or at least 99% but less than 100% identity.
(30) In one aspect, the amino acid sequence of the parent protease differs by no more than 10 amino acids, e.g., 1, 2, 3, 4, 5, 6, 7, 8, or 9, from the polypeptide with SEQ ID NO: 3.
(31) In another aspect, the parent comprises or consists of the amino acid sequence of SEQ ID NO: 3. In another aspect, the parent comprises or consists of amino acids 1 to 311 of SEQ ID NO: 2.
(32) In one aspect, the amino acid sequence of the parent protease differs by no more than 10 amino acids, e.g., 1, 2, 3, 4, 5, 6, 7, 8, or 9, from the polypeptide with SEQ ID NO: 4.
(33) In another aspect, the parent comprises or consists of the amino acid sequence of SEQ ID NO: 4.
(34) In one aspect, the amino acid sequence of the parent protease differs by no more than 10 amino acids, e.g., 1, 2, 3, 4, 5, 6, 7, 8, or 9, from the polypeptide with SEQ ID NO: 5.
(35) In another aspect, the parent comprises or consists of the amino acid sequence of SEQ ID NO: 5
(36) In another aspect, the parent protease is encoded by a polynucleotide that hybridizes under very low stringency conditions, low stringency conditions, medium stringency conditions, or high stringency conditions, or very high stringency conditions with (i) the mature polypeptide coding sequence of SEQ ID NO: 1, (ii) a sequence encoding the mature polypeptide of SEQ ID NO: 2, or (iii) the full-length complement of (i) or (ii), (Sambrook et al., 1989, Molecular Cloning, A Laboratory Manual, 2d edition, Cold Spring Harbor, N.Y.).
(37) The polynucleotide of SEQ ID NO: 1 or a subsequence thereof, as well as the polypeptide of SEQ ID NO: 3 or a fragment thereof may be used to design nucleic acid probes to identify and clone DNA encoding a parent from strains of different genera or species according to methods well known in the art. In particular, such probes can be used for hybridization with the genomic DNA or cDNA of a cell of interest, following standard Southern blotting procedures, in order to identify and isolate the corresponding gene therein. Such probes can be considerably shorter than the entire sequence, but should be at least 15, e.g., at least 25, at least 35, or at least 70 nucleotides in length. Preferably, the nucleic acid probe is at least 100 nucleotides in length, e.g., at least 200 nucleotides, at least 300 nucleotides, at least 400 nucleotides, at least 500 nucleotides, at least 600 nucleotides, at least 700 nucleotides, at least 800 nucleotides, or at least 900 nucleotides in length. Both DNA and RNA probes can be used. The probes are typically labeled for detecting the corresponding gene (for example, with .sup.32P, .sup.3H, .sup.35S, biotin, or avidin). Such probes are encompassed by the present invention.
(38) A genomic DNA or cDNA library prepared from such other strains may be screened for DNA that hybridizes with the probes described above and encodes a parent. Genomic or other DNA from such other strains may be separated by agarose or polyacrylamide gel electrophoresis, or other separation techniques. DNA from the libraries or the separated DNA may be transferred to and immobilized on nitrocellulose or other suitable carrier material. In order to identify a clone or DNA that hybridizes with SEQ ID NO: 1 or a subsequence thereof, the carrier material is used in a Southern blot.
(39) For purposes of the present invention, hybridization indicates that the polynucleotide hybridizes to a labeled nucleic acid probe corresponding to (i) SEQ ID NO: 1; (ii) the mature polypeptide coding sequence of SEQ ID NO: 1; (iii) a sequence encoding the mature polypeptide of SEQ ID NO: 2; (iv) the full-length complement thereof; or (v) a subsequence thereof; under very low to very high stringency conditions. Molecules to which the nucleic acid probe hybridizes under these conditions can be detected using, for example, X-ray film or any other detection means known in the art.
(40) In one aspect, the nucleic acid probe is the mature polypeptide coding sequence of SEQ ID NO: 1. In another aspect, the nucleotide acid probe is a 80 to 1140 nucleotides long fragment of SEQ ID NO: 1, e.g. 90, 100, 200, 300, 400, 500, 600, 700, 800, 900, 1000 or 1100 nucleotides long. In another aspect, the nucleic acid probe is a polynucleotide that encodes the polypeptide of SEQ ID NO: 2; the mature polypeptide thereof; or a fragment thereof. In another aspect, the nucleic acid probe is SEQ ID NO: 1 or a sequence encoding the mature polypeptide of SEQ ID NO: 2.
(41) In another embodiment, the parent is encoded by a polynucleotide having a sequence identity of at least 60%, such as at least 61%, at least 62%, at least 63%, at least 64%, at least 65%, at least 66%, at least 67%, at least 68%, at least 69%, at least 70%, at least 71%, at least 72%, at least 73%, at least 74%, at least 75%, at least 76%, at least 77%, at least 78%, at least 79%, at least 80%, at least 81%, at least 82%, at least 83%, at least 84%, at least 85%, at least 86%, at least 87%, at least 88%, at least 89%, at least 90%, at least 91%, at least 92%, at least 93%, at least 94%, at least 95%, at least 96%, at least 97%, at least 98% or at least 99% to the mature polypeptide coding sequence of SEQ ID NO: 1 or a sequence encoding the mature polypeptide of SEQ ID NO: 2.
(42) The polypeptide may be a hybrid polypeptide in which a region of one polypeptide is fused at the N-terminus or the C-terminus of a region of another polypeptide.
(43) The parent may be a fusion polypeptide or cleavable fusion polypeptide in which another polypeptide is fused at the N-terminus or the C-terminus of the polypeptide of the present invention. A fusion polypeptide is produced by fusing a polynucleotide encoding another polypeptide to a polynucleotide of the present invention. Techniques for producing fusion polypeptides are known in the art, and include ligating the coding sequences encoding the polypeptides so that they are in frame and that expression of the fusion polypeptide is under control of the same promoter(s) and terminator. Fusion polypeptides may also be constructed using intein technology in which fusion polypeptides are created post-translationally (Cooper et al., 1993, EMBO J. 12: 2575-2583; Dawson et al., 1994, Science 266: 776-779).
(44) A fusion polypeptide can further comprise a cleavage site between the two polypeptides. Upon secretion of the fusion protein, the site is cleaved releasing the two polypeptides. Examples of cleavage sites include, but are not limited to, the sites disclosed in Martin et al., 2003, J. Ind. Microbiol. Biotechnol. 3: 568-576; Svetina et al., 2000, J. Biotechnol. 76: 245-251; Rasmussen-Wilson et al., 1997, Appl. Environ. Microbiol. 63: 3488-3493; Ward et al., 1995, Biotechnology 13: 498-503; and Contreras et al., 1991, Biotechnology 9: 378-381; Eaton et al., 1986, Biochemistry 25: 505-512; Collins-Racie et al., 1995, Biotechnology 13: 982-987; Carter et al., 1989, Proteins: Structure, Function, and Genetics 6: 240-248; and Stevens, 2003, Drug Discovery World 4: 35-48.
(45) The parent may be obtained from organisms of any genus. For purposes of the present invention, the term “obtained from” as used herein in connection with a given source shall mean that the parent encoded by a polynucleotide is produced by the source or by a strain in which the polynucleotide from the source has been inserted. In one aspect, the parent is secreted extracellularly.
(46) The parent may be a bacterial protease. For example, the parent may be a Gram-positive bacterial polypeptide such as a Bacillus, Clostridium, Enterococcus, Geobacillus, Lactobacillus, Lactococcus, Oceanobacillus, Staphylococcus, Streptococcus, or Streptomyces protease, or a Gram-negative bacterial polypeptide such as a Campylobacter, E. coli, Flavobacterium, Fusobacterium, Helicobacter, Ilyobacter, Neisseria, Pseudomonas, Salmonella, or Ureaplasma protease.
(47) In one aspect, the parent is a Bacillus alkalophilus, Bacillus amyloliquefaciens, Bacillus brevis, Bacillus circulans, Bacillus clausfi, Bacillus coagulans, Bacillus firmus, Bacillus lautus, Bacillus lentus, Bacillus licheniformis, Bacillus megaterium, Bacillus pumilus, Bacillus stearothermophilus, Bacillus subtilis, or Bacillus thuringiensis protease
(48) In one aspect, the parent is a Bacillus sp. protease, e.g., the protease with SEQ ID NO: 3 or the mature polypeptide of SEQ ID NO 2.
(49) Strains of these species are readily accessible to the public in a number of culture collections, such as the American Type Culture Collection (ATCC), Deutsche Sammlung von Mikroorganismen and Zellkulturen GmbH (DSMZ), Centraalbureau Voor Schimmelcultures (CBS), and Agricultural Research Service Patent Culture Collection, Northern Regional Research Center (NRRL).
(50) The parent may be identified and obtained from other sources including microorganisms isolated from nature (e.g., soil, composts, water, etc.) or DNA samples obtained directly from natural materials (e.g., soil, composts, water, etc.) using the above-mentioned probes. Techniques for isolating microorganisms and DNA directly from natural habitats are well known in the art. A polynucleotide encoding a parent may then be obtained by similarly screening a genomic DNA or cDNA library of another microorganism or mixed DNA sample. Once a polynucleotide encoding a parent has been detected with the probe(s), the polynucleotide can be isolated or cloned by utilizing techniques that are known to those of ordinary skill in the art (see, e.g., Sambrook et al., 1989, supra).

(53) The variants can be prepared using any mutagenesis procedure known in the art, such as site-directed mutagenesis, synthetic gene construction, semi-synthetic gene construction, random mutagenesis, shuffling, etc.
(54) The present invention relates to a method for obtaining a protease variant having at least one improved property compared to SEQ ID NO 3, comprising introducing into a parent protease with at least 65% identity to SEQ ID NO: 3 a substitution at one or more positions: 2, 4, 5, 6, 16, 17, 18, 19, 24, 27, 39, 41, 43, 47, 50, 57, 58, 59, 63, 64, 65, 67, 70, 85, 86, 87, 92, 97, 108, 109, 111, 112, 114, 116, 118, 126, 127, 129, 130, 131, 132, 142, 143, 144, 147, 148, 149, 155, 156, 174, 177, 184, 185, 186, 194, 195, 196, 197, 198, 199, 200, 206, 207, 212, 214, 215, 218, 219, 220, 222, 225, 234, 236, 241, 245, 246, 247, 248, 264, 267, 268, 269, 270, 272, 274, 278, 279, 286, 287, 288, 293, 297 or 311 corresponding to positions of SEQ ID NO 3 wherein the variant has an amino acid sequence which is at least 70%, at least 80%, at least 85%, at least 90% or at least 95% identical to SEQ ID NO: 3; and recovering the variant.
(55) The present invention relates to a method for obtaining a protease variant having at least one improved property compared to SEQ ID NO 3, comprising introducing into a parent protease with at least 75% identity to SEQ ID NO: 3 a substitution at two or more positions: 2, 4, 5, 6, 16, 17, 18, 19, 24, 27, 39, 41, 43, 47, 50, 57, 58, 59, 63, 64, 65, 67, 70, 85, 86, 87, 92, 97, 108, 109, 111, 112, 114, 116, 118, 126, 127, 129, 130, 131, 132, 142, 143, 144, 147, 148, 149, 155, 156, 174, 177, 184, 185, 186, 194, 195, 196, 197, 198, 199, 200, 206, 207, 212, 214, 215, 218, 219, 220, 222, 225, 234, 236, 241, 245, 246, 247, 248, 264, 267, 268, 269, 270, 272, 274, 278, 279, 286, 287, 288, 293, 297 or 311 corresponding to positions of SEQ ID NO 3 wherein the variant has an amino acid sequence which is at least 70%, at least 80%, at least 85%, at least 90% or at least 95% identical to SEQ ID NO: 3; and recovering the variant.
(56) The variants of the invention may also be prepared by procedures such as those mentioned below.
(57) Site-directed mutagenesis is a technique in which one or more (e.g., several) mutations are introduced at one or more defined sites in a polynucleotide encoding the parent.
(58) Site-directed mutagenesis can be accomplished in vitro by PCR involving the use of oligonucleotide primers containing the desired mutation. Site-directed mutagenesis can also be performed in vitro by cassette mutagenesis involving the cleavage by a restriction enzyme at a site in the plasmid comprising a polynucleotide encoding the parent and subsequent ligation of an oligonucleotide containing the mutation in the polynucleotide. Usually the restriction enzyme that digests the plasmid and the oligonucleotide is the same, permitting sticky ends of the plasmid and the insert to ligate to one another. See, e.g., Scherer and Davis, 1979, Proc. Natl. Acad. Sci. USA 76: 4949-4955; and Barton et al., 1990, Nucleic Acids Res. 18: 7349-4966.
(59) Site-directed mutagenesis can also be accomplished in vivo by methods known in the art. See, e.g., U.S. Patent Application Publication No. 2004/0171154; Storici et al., 2001, Nature Biotechnol. 19: 773-776; Kren et al., 1998, Nat. Med. 4: 285-290; and Calissano and Macino, 1996, Fungal Genet. Newslett. 43: 15-16.
(60) Synthetic gene construction entails in vitro synthesis of a designed polynucleotide molecule to encode a polypeptide of interest. Gene synthesis can be performed utilizing a number of techniques, such as the multiplex microchip-based technology described by Tian et al. (2004, Nature 432: 1050-1054) and similar technologies wherein oligonucleotides are synthesized and assembled upon photo-programmable microfluidic chips.
(61) Single or multiple amino acid substitutions, deletions, and/or insertions can be made and tested using known methods of mutagenesis, recombination, and/or shuffling, followed by a relevant screening procedure, such as those disclosed by Reidhaar-Olson and Sauer, 1988, Science 241: 53-57; Bowie and Sauer, 1989, Proc. Natl. Acad. Sci. USA 86: 2152-2156; WO 95/17413; or WO 95/22625. Other methods that can be used include error-prone PCR, phage display (e.g., Lowman et al., 1991, Biochemistry 30: 10832-10837; U.S. Pat. No. 5,223,409; WO 92/06204) and region-directed mutagenesis (Derbyshire et al., 1986, Gene 46: 145; Ner et al., 1988, DNA 7: 127).
(62) Mutagenesis/shuffling methods can be combined with high-throughput, automated screening methods to detect activity of cloned, mutagenized polypeptides expressed by host cells (Ness et al., 1999, Nature Biotechnology 17: 893-896). Mutagenized DNA molecules that encode active polypeptides can be recovered from the host cells and rapidly sequenced using standard methods in the art. These methods allow the rapid determination of the importance of individual amino acid residues in a polypeptide.
(63) Semi-synthetic gene construction is accomplished by combining aspects of synthetic gene construction, and/or site-directed mutagenesis, and/or random mutagenesis, and/or shuffling. Semi-synthetic construction is typified by a process utilizing polynucleotide fragments that are synthesized, in combination with PCR techniques. Defined regions of genes may thus be synthesized de novo, while other regions may be amplified using site-specific mutagenic primers, while yet other regions may be subjected to error-prone PCR or non-error prone PCR amplification. Polynucleotide subsequences may then be shuffled.
(64) Polynucleotides
(65) The present invention also relates to isolated polynucleotides encoding a variant of the present invention.
(66) Nucleic Acid Constructs
(67) The present invention also relates to nucleic acid constructs comprising a polynucleotide encoding a variant of the present invention operably linked to one or more control sequences that direct the expression of the coding sequence in a suitable host cell under conditions compatible with the control sequences.
(68) The polynucleotide may be manipulated in a variety of ways to provide for expression of a variant. Manipulation of the polynucleotide prior to its insertion into a vector may be desirable or necessary depending on the expression vector. The techniques for modifying polynucleotides utilizing recombinant DNA methods are well known in the art.
(69) The control sequence may be a promoter, a polynucleotide which is recognized by a host cell for expression of the polynucleotide. The promoter contains transcriptional control sequences that mediate the expression of the variant. The promoter may be any polynucleotide that shows transcriptional activity in the host cell including mutant, truncated, and hybrid promoters, and may be obtained from genes encoding extracellular or intracellular polypeptides either homologous or heterologous to the host cell.
(70) Examples of suitable promoters for directing transcription of the nucleic acid constructs of the present invention in a bacterial host cell are the promoters obtained from the Bacillus amyloliquefaciens alpha-amylase gene (amyQ), Bacillus licheniformis alpha-amylase gene (amyL), Bacillus licheniformis penicillinase gene (penP), Bacillus stearothermophilus maltogenic amylase gene (amyM), Bacillus subtilis levansucrase gene (sacB), Bacillus subtilis xylA and xylB genes, Bacillus thuringiensis cryIIIA gene (Agaisse and Lereclus, 1994, Molecular Microbiology 13: 97-107), E. coli lac operon, E. coli trc promoter (Egon et al., 1988, Gene 69: 301-315), Streptomyces coelicolor agarase gene (dagA), and prokaryotic beta-lactamase gene (Villa-Kamaroff et al., 1978, Proc. Natl. Acad. Sci. USA 75: 3727-3731), as well as the tac promoter (DeBoer et al., 1983, Proc. Natl. Acad. Sci. USA 80: 21-25). Further promoters are described in “Useful proteins from recombinant bacteria” in Gilbert et al., 1980, Scientific American 242: 74-94; and in Sambrook et al., 1989, supra. Examples of tandem promoters are disclosed in WO 99/43835.
(71) The control sequence may also be a transcription terminator, which is recognized by a host cell to terminate transcription. The terminator sequence is operably linked to the 3′-terminus of the polynucleotide encoding the variant. Any terminator that is functional in the host cell may be used.
(72) Preferred terminators for bacterial host cells are obtained from the genes for Bacillus clausii alkaline protease (aprH), Bacillus licheniformis alpha-amylase (amyL), and Escherichia coli ribosomal RNA (rrnB).
(73) The control sequence may also be an mRNA stabilizer region downstream of a promoter and upstream of the coding sequence of a gene which increases expression of the gene.
(74) Examples of suitable mRNA stabilizer regions are obtained from a Bacillus thuringiensis cryIIIA gene (WO 94/25612) and a Bacillus subtilis SP82 gene (Hue et al., 1995, Journal of Bacteriology 177: 3465-3471).
(75) The control sequence may also be a signal peptide coding region that encodes a signal peptide linked to the N-terminus of a variant and directs the variant into the cell's secretory pathway. The 5′-end of the coding sequence of the polynucleotide may inherently contain a signal peptide coding sequence naturally linked in translation reading frame with the segment of the coding sequence that encodes the variant. Alternatively, the 5′-end of the coding sequence may contain a signal peptide coding sequence that is foreign to the coding sequence. A foreign signal peptide coding sequence may be required where the coding sequence does not naturally contain a signal peptide coding sequence. Alternatively, a foreign signal peptide coding sequence may simply replace the natural signal peptide coding sequence in order to enhance secretion of the variant. However, any signal peptide coding sequence that directs the expressed variant into the secretory pathway of a host cell may be used.
(76) Effective signal peptide coding sequences for bacterial host cells are the signal peptide coding sequences obtained from the genes for Bacillus NCIB 11837 maltogenic amylase, Bacillus licheniformis subtilisin, Bacillus licheniformis beta-lactamase, Bacillus stearothermophilus alpha-amylase, Bacillus stearothermophilus neutral proteases (nprT, nprS, nprM), and Bacillus subtilis prsA. Further signal peptides are described by Simonen and Palva, 1993, Microbiological Reviews 57: 109-137.
(77) The control sequence may also be a propeptide coding sequence that encodes a propeptide positioned at the N-terminus of a variant. The resultant polypeptide is known as a proenzyme or propolypeptide (or a zymogen in some cases). A propolypeptide is generally inactive and can be converted to an active polypeptide by catalytic or autocatalytic cleavage of the propeptide from the propolypeptide. The propeptide coding sequence may be obtained from the genes for Bacillus subtilis alkaline protease (aprE), Bacillus subtilis neutral protease (nprT), Myceliophthora thermophila laccase (WO 95/33836), Rhizomucor miehei aspartic proteinase, and Saccharomyces cerevisiae alpha-factor.
(78) Where both signal peptide and propeptide sequences are present, the propeptide sequence is positioned next to the N-terminus of the variant and the signal peptide sequence is positioned next to the N-terminus of the propeptide sequence.
(79) It may also be desirable to add regulatory sequences that regulate expression of the variant relative to the growth of the host cell. Examples of regulatory systems are those that cause expression of the gene to be turned on or off in response to a chemical or physical stimulus, including the presence of a regulatory compound. Regulatory systems in prokaryotic systems include the lac, tac, and trp operator systems.
(80) Expression Vectors
(81) The present invention also relates to recombinant expression vectors comprising a polynucleotide encoding a variant of the present invention, a promoter, and transcriptional and translational stop signals. The various nucleotide and control sequences may be joined together to produce a recombinant expression vector that may include one or more convenient restriction sites to allow for insertion or substitution of the polynucleotide encoding the variant at such sites. Alternatively, the polynucleotide may be expressed by inserting the polynucleotide or a nucleic acid construct comprising the polynucleotide into an appropriate vector for expression. In creating the expression vector, the coding sequence is located in the vector so that the coding sequence is operably linked with the appropriate control sequences for expression.
(82) The recombinant expression vector may be any vector (e.g., a plasmid or virus) that can be conveniently subjected to recombinant DNA procedures and can bring about expression of the polynucleotide. The choice of the vector will typically depend on the compatibility of the vector with the host cell into which the vector is to be introduced. The vector may be a linear or closed circular plasmid.
(83) The vector may be an autonomously replicating vector, i.e., a vector that exists as an extrachromosomal entity, the replication of which is independent of chromosomal replication, e.g., a plasmid, an extrachromosomal element, a minichromosome, or an artificial chromosome. The vector may contain any means for assuring self-replication. Alternatively, the vector may be one that, when introduced into the host cell, is integrated into the genome and replicated together with the chromosome(s) into which it has been integrated. Furthermore, a single vector or plasmid or two or more vectors or plasmids that together contain the total DNA to be introduced into the genome of the host cell, or a transposon, may be used.
(84) The vector preferably contains one or more selectable markers that permit easy selection of transformed, transfected, transduced, or the like cells. A selectable marker is a gene the product of which provides for biocide or viral resistance, resistance to heavy metals, prototrophy to auxotrophs, and the like.
(85) Examples of bacterial selectable markers are Bacillus licheniformis or Bacillus subtilis dal genes, or markers that confer antibiotic resistance such as ampicillin, chloramphenicol, kanamycin, neomycin, spectinomycin or tetracycline resistance.
(86) The vector preferably contains an element(s) that permits integration of the vector into the host cell's genome or autonomous replication of the vector in the cell independent of the genome.
(87) For integration into the host cell genome, the vector may rely on the polynucleotide's sequence encoding the variant or any other element of the vector for integration into the genome by homologous or non-homologous recombination. Alternatively, the vector may contain additional polynucleotides for directing integration by homologous recombination into the genome of the host cell at a precise location(s) in the chromosome(s). To increase the likelihood of integration at a precise location, the integrational elements should contain a sufficient number of nucleic acids, such as 100 to 10,000 base pairs, 400 to 10,000 base pairs, and 800 to 10,000 base pairs, which have a high degree of sequence identity to the corresponding target sequence to enhance the probability of homologous recombination. The integrational elements may be any sequence that is homologous with the target sequence in the genome of the host cell. Furthermore, the integrational elements may be non-encoding or encoding polynucleotides. On the other hand, the vector may be integrated into the genome of the host cell by non-homologous recombination.
(88) For autonomous replication, the vector may further comprise an origin of replication enabling the vector to replicate autonomously in the host cell in question. The origin of replication may be any plasmid replicator mediating autonomous replication that functions in a cell. The term “origin of replication” or “plasmid replicator” means a polynucleotide that enables a plasmid or vector to replicate in vivo.
(89) Examples of bacterial origins of replication are the origins of replication of plasmids pBR322, pUC19, pACYC177, and pACYC184 permitting replication in E. coli, and pUB110, pE194, pTA1060, and pAMß1 permitting replication in Bacillus.
(90) More than one copy of a polynucleotide of the present invention may be inserted into a host cell to increase production of a variant. An increase in the copy number of the polynucleotide can be obtained by integrating at least one additional copy of the sequence into the host cell genome or by including an amplifiable selectable marker gene with the polynucleotide where cells containing amplified copies of the selectable marker gene, and thereby additional copies of the polynucleotide, can be selected for by cultivating the cells in the presence of the appropriate selectable agent.
(91) The procedures used to ligate the elements described above to construct the recombinant expression vectors of the present invention are well known to one skilled in the art (see, e.g., Sambrook et al., 1989, supra).
(92) Host Cells
(93) The present invention also relates to recombinant host cells, comprising a polynucleotide encoding a variant of the present invention operably linked to one or more control sequences that direct the production of a variant of the present invention. A construct or vector comprising a polynucleotide is introduced into a host cell so that the construct or vector is maintained as a chromosomal integrant or as a self-replicating extra-chromosomal vector as described earlier. The term “host cell” encompasses any progeny of a parent cell that is not identical to the parent cell due to mutations that occur during replication. The choice of a host cell will to a large extent depend upon the gene encoding the variant and its source.
(94) The host cell may be any cell useful in the recombinant production of a variant, e.g., a prokaryote or a eukaryote.
(95) The prokaryotic host cell may be any Gram-positive or Gram-negative bacterium. Gram-positive bacteria include, but are not limited to, Bacillus, Clostridium, Enterococcus, Geobacillus, Lactobacillus, Lactococcus, Oceanobacillus, Staphylococcus, Streptococcus, and Streptomyces. Gram-negative bacteria include, but are not limited to, Campylobacter, E. coli, Flavobacterium, Fusobacterium, Helicobacter, Ilyobacter, Neisseria, Pseudomonas, Salmonella, and Ureaplasma.
(96) The bacterial host cell may be any Bacillus cell including, but not limited to, Bacillus alkalophilus, Bacillus amyloliquefaciens, Bacillus brevis, Bacillus circulans, Bacillus clausii, Bacillus coagulans, Bacillus firmus, Bacillus lautus, Bacillus lentus, Bacillus licheniformis, Bacillus megaterium, Bacillus pumilus, Bacillus stearothermophilus, Bacillus subtilis, and Bacillus thuringiensis cells.
(97) The bacterial host cell may also be any Streptococcus cell including, but not limited to, Streptococcus equisimilis, Streptococcus pyogenes, Streptococcus uberis, and Streptococcus equi subsp. Zooepidemicus cells.
(98) The bacterial host cell may also be any Streptomyces cell, including, but not limited to, Streptomyces achromogenes, Streptomyces avermitilis, Streptomyces coelicolor, Streptomyces griseus, and Streptomyces lividans cells.
(99) The introduction of DNA into a Bacillus cell may be effected by protoplast transformation (see, e.g., Chang and Cohen, 1979, Mol. Gen. Genet. 168: 111-115), competent cell transformation (see, e.g., Young and Spizizen, 1961, J. Bacteriol. 81: 823-829, or Dubnau and Davidoff-Abelson, 1971, J. Mol. Biol. 56: 209-221), electroporation (see, e.g., Shigekawa and Dower, 1988, Biotechniques 6: 742-751), or conjugation (see, e.g., Koehler and Thorne, 1987, J. Bacteriol. 169: 5271-5278). The introduction of DNA into an E. coli cell may be effected by protoplast transformation (see, e.g., Hanahan, 1983, J. Mol. Biol. 166: 557-580) or electroporation (see, e.g., Dower et al., 1988, Nucleic Acids Res. 16: 6127-6145). The introduction of DNA into a Streptomyces cell may be effected by protoplast transformation, electroporation (see, e.g., Gong et al., 2004, Folia Microbiol. (Praha) 49: 399-405), conjugation (see, e.g., Mazodier et al., 1989, J. Bacteriol. 171: 3583-3585), or transduction (see, e.g., Burke et al., 2001, Proc. Natl. Acad. Sci. USA 98: 6289-6294). The introduction of DNA into a Pseudomonas cell may be effected by electroporation (see, e.g., Choi et al., 2006, J. Microbiol. Methods 64: 391-397), or conjugation (see, e.g., Pinedo and Smets, 2005, Appl. Environ. Microbiol. 71: 51-57). The introduction of DNA into a Streptococcus cell may be effected by natural competence (see, e.g., Perry and Kuramitsu, 1981, Infect. Immun. 32: 1295-1297), protoplast transformation (see, e.g., Catt and Jollick, 1991, Microbios 68: 189-207), electroporation (see, e.g., Buckley et al., 1999, Appl. Environ. Microbiol. 65: 3800-3804) or conjugation (see, e.g., Clewell, 1981, Microbiol. Rev. 45: 409-436). However, any method known in the art for introducing DNA into a host cell can be used.
(100) Methods of Production
(101) The present invention also relates to methods of producing a variant, comprising: (a) cultivating a host cell of the present invention under conditions suitable for expression of the variant; and (b) recovering the variant.
(102) The host cells are cultivated in a nutrient medium suitable for production of the variant using methods known in the art. For example, the cell may be cultivated by shake flask cultivation, or small-scale or large-scale fermentation (including continuous, batch, fed-batch, or solid state fermentations) in laboratory or industrial fermentors performed in a suitable medium and under conditions allowing the variant to be expressed and/or isolated. The cultivation takes place in a suitable nutrient medium comprising carbon and nitrogen sources and inorganic salts, using procedures known in the art. Suitable media are available from commercial suppliers or may be prepared according to published compositions (e.g., in catalogues of the American Type Culture Collection). If the variant is secreted into the nutrient medium, the variant can be recovered directly from the medium. If the variant is not secreted, it can be recovered from cell lysates.
(103) The variant may be detected using methods known in the art that are specific for the variants with protease activity. These detection methods include, but are not limited to, use of specific antibodies, formation of an enzyme product, or disappearance of an enzyme substrate. For example, an enzyme assay may be used to determine the activity of the variant.
(104) The variant may be recovered using methods known in the art. For example, the variant may be recovered from the nutrient medium by conventional procedures including, but not limited to, collection, centrifugation, filtration, extraction, spray-drying, evaporation, or precipitation.
(105) The variant may be purified by a variety of procedures known in the art including, but not limited to, chromatography (e.g., ion exchange, affinity, hydrophobic, chromatofocusing, and size exclusion), electrophoretic procedures (e.g., preparative isoelectric focusing), differential solubility (e.g., ammonium sulfate precipitation), SDS-PAGE, or extraction (see, e.g., Protein Purification, Janson and Ryden, editors, VCH Publishers, New York, 1989) to obtain substantially pure variants.
(106) In an alternative aspect, the variant is not recovered, but rather a host cell of the present invention expressing the variant is used as a source of the variant.
(107) Compositions
(108) In one certain aspect, the variants according to the invention has improved stability in detergents compared to the parent enzyme or compared to a protease having the identical amino acid sequence of said variant but not having the alterations at one or more of said specified positions or compared to a protease with SEQ ID NO 3, wherein stability is measured in Example 2 as described in “Material and Methods” herein.
(109) Besides enzymes the detergent compositions may comprise additional components. The choice of additional components is within the skill of the artisan and includes conventional ingredients, including the exemplary non-limiting components set forth below. The choice of components may include, for fabric care, the consideration of the type of fabric to be cleaned, the type and/or degree of soiling, the temperature at which cleaning is to take place, and the formulation of the detergent product. Although components mentioned below are categorized by general header according to a particular functionality, this is not to be construed as a limitation, as a component may comprise additional functionalities as will be appreciated by the skilled artisan.
(110) Detergent Compositions of the Present Invention
(111) The variants of the present invention may be added to a detergent composition in an amount corresponding to 0.001-100 mg of protein, such as 0.01-100 mg of protein, preferably 0.005-50 mg of protein, more preferably 0.01-25 mg of protein, even more preferably 0.05-10 mg of protein, most preferably 0.05-5 mg of protein, and even most preferably 0.01-1 mg of protein per liter of wash liquor.
(112) The variants of the present invention may be stabilized using stabilizing agents, which may be selected from the group containing propylene glycol, glycerol, a sugar, a sugar alcohol, lactic acid, boric acid, borate and phenyl boronic acid derivates, such as 4-formylphenylboronic acid (4-FPBA).
(113) The variants according to the invention may also be stabilized using peptide aldehydes or ketones such as described in WO 2005/105826 and WO 2009/118375. A variant of the present invention may also be incorporated in the detergent formulations disclosed in WO 97/07202, which is hereby incorporated by reference.
(114) Surfactants

(121) Hydrotropes
(122) A hydrotrope is a compound that solubilises hydrophobic compounds in aqueous solutions (or oppositely, polar substances in a non-polar environment). Typically, hydrotropes have both hydrophilic and a hydrophobic character (so-called amphiphilic properties as known from surfactants); however the molecular structure of hydrotropes generally do not favor spontaneous self-aggregation, see e.g. review by Hodgdon and Kaler (2007), Current Opinion in Colloid & Interface Science 12: 121-128. Hydrotropes do not display a critical concentration above which self-aggregation occurs as found for surfactants and lipids forming miceller, lamellar or other well defined meso-phases. Instead, many hydrotropes show a continuous-type aggregation process where the sizes of aggregates grow as concentration increases. However, many hydrotropes alter the phase behavior, stability, and colloidal properties of systems containing substances of polar and non-polar character, including mixtures of water, oil, surfactants, and polymers. Hydrotropes are classically used across industries from pharma, personal care, food, to technical applications. Use of hydrotropes in detergent compositions allow for example more concentrated formulations of surfactants (as in the process of compacting liquid detergents by removing water) without inducing undesired phenomena such as phase separation or high viscosity.
(123) The detergent may contain 0-5% by weight, such as about 0.5 to about 5%, or about 3% to about 5%, of a hydrotrope. Any hydrotrope known in the art for use in detergents may be utilized. Non-limiting examples of hydrotropes include sodium benzene sulfonate, sodium p-toluene sulfonates (STS), sodium xylene sulfonates (SXS), sodium cumene sulfonates (SCS), sodium cymene sulfonate, amine oxides, alcohols and polyglycolethers, sodium hydroxynaphthoate, sodium hydroxynaphthalene sulfonate, sodium ethylhexyl sulfate, and combinations thereof.

In a dish wash detergent, the level of builder is typically 40-65%, particularly 50-65%. The builder and/or co-builder may particularly be a chelating agent that forms water-soluble complexes with Ca and Mg. Any builder and/or co-builder known in the art for use in laundry, ADW and hard surfaces cleaning detergents may be utilized. Non-limiting examples of builders include zeolites, diphosphates (pyrophosphates), triphosphates such as sodium triphosphate (STP or STPP), carbonates such as sodium carbonate, soluble silicates such as sodium metasilicate, layered silicates (e.g., SKS-6 from Hoechst), ethanolamines such as 2-aminoethan-1-ol (MEA), iminodiethanol (DEA) and 2,2′,2″-nitrilotriethanol (TEA), and carboxymethylinulin (CMI), and combinations thereof.

(127) Bleaching Systems
(128) The detergent may contain 0-10% by weight, such as about 1% to about 5%, of a bleaching system. Any bleaching system known in the art for use in laundry, ADW and hard surfaces cleaning detergents may be utilized. Suitable bleaching system components include bleaching catalysts, photobleaches, bleach activators, sources of hydrogen peroxide such as sodium percarbonate and sodium perborates, preformed peracids and mixtures thereof. Suitable preformed peracids include, but are not limited to, peroxycarboxylic acids and salts, percarbonic acids and salts, perimidic acids and salts, peroxymonosulfuric acids and salts, for example, Oxone®, and mixtures thereof. Non-limiting examples of bleaching systems include peroxide-based bleaching systems, which may comprise, for example, an inorganic salt, including alkali metal salts such as sodium salts of perborate (usually mono- or tetra-hydrate), percarbonate, persulfate, perphosphate, persilicate salts, in combination with a peracid-forming bleach activator. By bleach activator is meant herein a compound which reacts with peroxygen bleach like hydrogen peroxide to form a peracid. The peracid thus formed constitutes the activated bleach. Suitable bleach activators to be used herein include those belonging to the class of esters amides, imides or anhydrides. Suitable examples are tetracetyl ethylene diamine (TAED), sodium 3,5,5 trimethyl hexanoyloxybenzene sulphonat, diperoxy dodecanoic acid, 4-(dodecanoyloxy)benzenesulfonate (LOBS), 4-(decanoyloxy)benzenesulfonate, 4-(decanoyloxy)benzoate (DOBS), 4-(3,5,5-trimethylhexanoyloxy)benzenesulfonate (ISONOBS), tetraacetylethylenediamine (TAED) and 4-(nonanoyloxy)benzenesulfonate (NOBS), and/or those disclosed in WO98/17767. A particular family of bleach activators of interest was disclosed in EP624154 and particulary preferred in that family is acetyl triethyl citrate (ATC). ATC or a short chain triglyceride like Triacin has the advantage that it is environmental friendly as it eventually degrades into citric acid and alcohol. Furthermore acethyl triethyl citrate and triacetin has a good hydrolytical stability in the product upon storage and it is an efficient bleach activator. Finally ATC provides a good building capacity to the laundry additive. Alternatively, the bleaching system may comprise peroxyacids of, for example, the amide, imide, or sulfone type. The bleaching system may also comprise peracids such as 6-(phthaloylamino)percapronic acid (PAP). The bleaching system may also include a bleach catalyst.

The at least one protease variant preferably has increased detergent stability relative to the parent or relative to a protease parent having the identical amino acid sequence of said variant but not having the substitutions at one or more of said positions when tested in Assay B described in example 2, as described under “Material and Methods”.
(215) A detergent composition may be formulated, for example, as a hand or machine laundry detergent composition including a laundry additive composition suitable for pre-treatment of stained fabrics and a rinse added fabric softener composition, or be formulated as a detergent composition for use in general household hard surface cleaning operations, or be formulated for hand or machine dishwashing operations.
(216) A cleaning process or the textile care process may for example be a laundry process, a dishwashing process or cleaning of hard surfaces such as bathroom tiles, floors, table tops, drains, sinks and washbasins. Laundry processes can for example be household laundering, but it may also be industrial laundering. A process for laundering of fabrics and/or garments may be a process comprises treating fabrics with a washing solution containing a detergent composition, and at least one protease variant. A cleaning process or a textile care process can for example be carried out in a machine washing process or in a manual washing process. The washing solution can for example be an aqueous washing solution containing a detergent composition.
(217) The fabrics and/or garments subjected to a washing, cleaning or textile care process may be conventional washable laundry, for example household laundry. Preferably, the major part of the laundry is garments and fabrics, including knits, woven, denims, non-woven, felts, yarns, and towelling. The fabrics may be cellulose based such as natural cellulosics, including cotton, flax, linen, jute, ramie, sisal or coir or manmade cellulosics (e.g., originating from wood pulp) including viscose/rayon, ramie, cellulose acetate fibers (tricell), lyocell or blends thereof. The fabrics may also be non-cellulose based such as natural polyamides including wool, camel, cashmere, mohair, rabit and silk or synthetic polymer such as nylon, aramid, polyester, acrylic, polypropylen and spandex/elastane, or blends thereof as well as blend of cellulose based and non-cellulose based fibers. Examples of blends are blends of cotton and/or rayon/viscose with one or more companion material such as wool, synthetic fibers (e.g., polyamide fibers, acrylic fibers, polyester fibers, polyvinyl alcohol fibers, polyvinyl chloride fibers, polyurethane fibers, polyurea fibers, aramid fibers), and cellulose-containing fibers (e.g., rayon/viscose, ramie, flax, linen, jute, cellulose acetate fibers, lyocell).
(218) The last few years there has been an increasing interest in replacing components in detergents, which is derived from petrochemicals with renewable biological components such as enzymes and polypeptides without compromising the wash performance. When the components of detergent compositions change new enzyme activities or new enzymes having alternative and/or improved properties compared to the common used detergent enzymes such as proteases, lipases and amylases is needed to achieve a similar or improved wash performance when compared to the traditional detergent compositions.
(219) Proteases and variants hereof are usable in proteinaceous stain removing processes. The proteinaceous stains may be stains such as food stains, e.g., baby food, sebum, cocoa, egg, blood, milk, ink, grass, or a combination hereof.
(220) Typical detergent compositions include various components in addition to the enzymes, these components have different effects, some components like the surfactants lower the surface tension in the detergent, which allows the stain being cleaned to be lifted and dispersed and then washed away, other components like bleach systems remove discolor often by oxidation and many bleaches also have strong bactericidal properties, and are used for disinfecting and sterilizing. Yet other components like builder and chelator softens, e.g., the wash water by removing the metal ions form the liquid.
(221) The enzyme compositions may further comprise at least one or more of the following: a surfactant, a builder, a chelator or chelating agent, bleach system or bleach component in laundry or dish wash.
(222) The amount of a surfactant, a builder, a chelator or chelating agent, bleach system and/or bleach component may be reduced compared to amount of surfactant, builder, chelator or chelating agent, bleach system and/or bleach component used without the added protease variant of the invention. Preferably the at least one component which is a surfactant, a builder, a chelator or chelating agent, bleach system and/or bleach component is present in an amount that is 1% less, such as 2% less, such as 3% less, such as 4% less, such as 5% less, such as 6% less, such as 7% less, such as 8% less, such as 9% less, such as 10% less, such as 15% less, such as 20% less, such as 25% less, such as 30% less, such as 35% less, such as 40% less, such as 45% less, such as 50% less than the amount of the component in the system without the addition of protease variants of the invention, such as a conventional amount of such component. Detergent compositions may also be composition which is free of at least one component which is a surfactant, a builder, a chelator or chelating agent, bleach system or bleach component and/or polymer.

(229) Materials and Methods
(230) Protease Activity Assays
(231) 1) Suc-AAPF-pNA Activity Assay:
(232) The proteolytic activity can be determined by a method employing the Suc-AAPF-pNA substrate. Suc-AAPF-pNA is an abbreviation for N-Succinyl-Alanine-Alanine-Proline-Phenylalanine-p-Nitroanilide, and it is a blocked peptide which can be cleaved by endo-proteases. Following cleavage a free pNA molecule is liberated and it has a yellow colour and thus can be measured by visible spectrophotometry at wavelength 405 nm. The Suc-AAPF-PNA substrate is manufactured by Bachem (cat. no. L1400, dissolved in DMSO).
(233) The protease sample to be analyzed was diluted in residual activity buffer (100 mM Tris pH 8.6). The assay was performed by transferring 30 μl of diluted enzyme samples to 96 well microtiter plate and adding 70 μl substrate working solution (0.72 mg/ml in 100 mM Tris pH8.6). The solution was mixed at room temperature and absorption is measured every 20 sec. over 5 minutes at OD 405 nm.
(234) The slope (absorbance per minute) of the time dependent absorption-curve is directly proportional to the activity of the protease in question under the given set of conditions. The protease sample should be diluted to a level where the slope is linear.

General Molecular Biology Methods:
(236) Unless otherwise mentioned the DNA manipulations and transformations were performed using standard methods of molecular biology (Sambrook et al. (1989); Ausubel et al. (1995); Harwood and Cutting (1990).
Example 1: Construction of TY145 Variants by Site-Directed Mutagenesis
(237) Site-directed variants were constructed of the TY145 protease (SEQ ID NO: 3) comprising specific substitutions according to the invention. The variants were made by traditional cloning of DNA fragments (Sambrook et al., Molecular Cloning: A Laboratory Manual, 2nd Ed., Cold Spring Harbor, 1989) using PCR together with properly designed mutagenic oligonucleotides that introduced the desired mutations in the resulting sequence.
(238) Mutagenic oligos were designed corresponding to the DNA sequence flanking the desired site(s) of mutation, separated by the DNA base pairs defining the insertions/deletions/substitutions, and purchased from an oligo vendor such as Life Technologies. In this manner, the variants listed in Table 2 below were constructed and produced.
(239) In order to test TY145 protease variants of the invention, the mutated DNA comprising a variant of the invention was transformed into a competent B. subtilis strain and fermented using standard protocols (liquid media, 3-4 days, 30° C.). The culture broth was centrifuged (26000×g, 20 min) and the supernatant was carefully decanted from the precipitate. The supernatant was filtered through a Nalgene 0.2 μm filtration unit in order to remove the rest of the Bacillus host cells. The 0.2 μm filtrate was mixed 1:1 with 3.0M (NH4)2SO4 and the mixture was applied to a Phenyl-sepharose FF (high sub) column (from GE Healthcare) equilibrated in 100 mM H3BO3, 10 mM MES/NaOH, 2 mM CaCl2, 1.5M (NH4)2SO4, pH 6.0. After washing the column with the equilibration buffer, the protease was step-eluted with 100 mM H3BO3, 10 mM MES, 2 mM CaCl2, pH 6.0. The eluted peak (containing the protease activity) was collected and applied to a Bacitracin agarose column (from Upfront chromatography) equilibrated in 100 mM H3BO3, 10 mM MES, 2 mM CaCl2, pH 6.0. After washing the column extensively with the equilibration buffer, the protease was eluted with 100 mM H3BO3, 10 mM MES, 2 mM CaCl2, 1M NaCl, pH 6.0 with 25% (v/v) 2-propanol. The elution peak (containing the protease activity) was transferred to 20 mM MES, 2 mM CaCl2, pH 6.0 on a G25 sephadex column (from GE Healthcare). The G25 transferred peak was the purified preparation and was used for further experiments.

Example 2: Wash Testing of Variants by Automatic Mechanical Stress Assay (AMSA)
(241) Washing experiments are performed in order to assess the wash performance of selected protease variants in laundry detergent. The proteases of the present application were tested using the Automatic Mechanical Stress Assay (AMSA). With the AMSA, the wash performance of many small volume enzyme-detergent solutions can be examined. The AMSA plate has a number of slots for test solutions and a lid that firmly squeezes the textile swatch to be washed against the slot openings. During the wash, the plate, test solutions, textile swatch and lid are vigorously shaken to bring the test solution in contact with the soiled textile swatch and apply mechanical stress in a regular, periodic oscillating manner. For further description see WO 02/42740 especially the paragraph “Special method embodiments” on page 23-24.
(242) The experiment was conducted under the experimental conditions as specified in Table 3 below.
(243) TABLE-US-00003 TABLE 3 AMSA Experimental Conditions Detergent Model detergent B Detergent dosage 3.33 g/L Test solution volume 160 μL Wash time 20 minutes Temperature 20° C. Water hardness 15° dH Enzyme concentration in test solution 30-60 nM Test material Chocolate milk and soot swatch (PC-03) Blood Milk Ink swatch (EMPA117) with extra heat treatment, Full egg with pigment swatch (CS-37)
Water hardness was adjusted to 15° dH by addition of CaCl2, MgCl2, and NaHCO3 (Ca2+:Mg2+:CO32−=4:1:7.5) to the test system. The swatch textiles were flushed in tap water and dried after washing.
(244) The performance of an enzyme variant is measured as the brightness of the colour of the textile washed with that specific protease. Brightness can also be expressed as the intensity of the light reflected from the sample when illuminated with white light. When the sample is stained the intensity of the reflected light is lower, than that of a clean sample. Therefore the intensity of the reflected light can be used to measure wash performance of a protease. Color measurements were made with a professional flatbed scanner (EPSON EXPRESSION 10000XL, Atea NS, Lautrupvang 6, 2750 Ballerup, Denmark), which is used to capture an image of the washed melamine tiles.
(245) To extract a value for the light intensity from the scanned images, a special designed software application is used (Novozymes Colour Vector Analyzer). The program retrieves the 24 bit pixel values from the image and converts them into values for red, green and blue (RGB). The intensity value (Int) is calculated by adding the RGB values together as vectors and then taking the length of the resulting vector:
Int=√{square root over (r.sup.2+g.sup.2+b.sup.2)}
Textiles
(246) Standard chocolate milk and soot textile swatches (PC-03), blood milk ink (EMPA117) with extra heat treatment and full egg with pigment swatch (CS-37) textile swatches were obtained from Center For Testmaterials BV, P.O. Box 120, 3133 KT Vlaardingen, the Netherlands.
(247) The AMSA relative wash performance is then calculated for each variant by dividing the intensity value for textile washed with the variant by the intensity value for the textile washed with the parent backbone
(248)
(249) Having the AMSA relative wash performance for each variant, it is possible to calculate the effect of a single mutation, if data are available for at least two variants that differ only by that mutation (Table 4). In this case, the AMSA relative wash performance for the mutation is calculated:
