[0052] Hereinafter, the bacteria or bacterial strains used in an embodiment as described herein may be referred to as hosts.

Ability to Produce and Secrete Heterologous Proteins

[0053] The bacteria used in an embodiment as described herein have the ability to produce and secrete a heterologous protein. Moreover, the bacteria used in an embodiment as described herein preferably have the ability to extracellularly secrete a heterologous protein through heterologous Tat proteins. The ability to produce and secrete a heterologous protein can be acquired, for example, by the bacteria used in an embodiment as described herein having a genetic construct for the production and secretion of a heterologous protein.

[0054] In an embodiment as described herein, the term protein is a concept that includes not only proteins but also oligopeptides and polypeptides.

[0055] As disclosed herein, the secretion of a protein or peptide refers to the transfer of the protein or peptide molecules outside the bacterial cell body (extracellularly), encompassing not only cases where eventually the protein or peptide molecules are completely released into the medium but also cases where only some of them are present extracellularly or on the surface of the bacterial body.

[0056] In an embodiment as described herein, having the ability to produce and secrete a heterologous protein means that when the bacteria of an embodiment as described herein are cultured in a medium, the bacteria can produce a heterologous protein and secrete it outside the bacterial cell body.

Heterologous Protein

[0057] In an embodiment as described herein, heterologous protein refers to a foreign protein for the bacteria used in an embodiment as described herein. The heterologous protein is preferably a protein derived from an organism other than bacteria selected from the group consisting of the genus Bifidobacterium, the genus Lactococcus, the genus Lactobacillus, the genus Limosilactobacillus, and the genus Staphylococcus. The heterologous protein may be a protein derived from animals, a protein derived from plants, a protein derived from bacteria, a protein derived from fungi, or a protein derived from viruses. Among these, the heterologous protein is preferably a protein derived from animals or a protein derived from bacteria, further more preferably a protein derived from animals, and particularly more preferably a protein derived from mammals. In addition, a protein derived from mammals is preferably a protein derived from humans.

[0058] Also, the heterologous protein may be a protein having the same amino acid sequence as the protein endogenous in organisms other than bacteria of the genus Bifidobacterium, the genus Lactococcus, the genus Lactobacillus, the genus Limosilactobacillus, and/or the genus Staphylococcus, or it may be a protein that has modified the amino acid sequence of the protein endogenous in the aforementioned organisms. Examples of proteins that have modified the amino acid sequence of proteins endogenous in the aforementioned organisms include proteins with improved enzymatic activity.

[0059] There are no particular limitations on the heterologous protein produced and secreted by the bacteria of an embodiment as described herein, and any desired heterologous protein may be used. Specific examples of a heterologous protein include human-derived fibroblast growth factors (FGF) such as human-derived basic fibroblast growth factor (bFGF or FGF2) and human-derived acidic fibroblast growth factor (aFGF or FGF1), protein-glutaminase, isomaltodextranase, and trans-glutaminase. Among these, it is preferable to include FGF, preferable to include at least one selected from FGF2 and FGF1, more preferable to be at least one selected from FGF2 and FGF1, and further preferable to be FGF2.

[0060] The heterologous protein may have a pre-sequence (signal sequence) and/or pro-sequence that can be possessed in its natural state, or it may be such that such pre-sequence and/or pro-sequence has been removed. Also, the heterologous protein may be one to which a sequence not originally possessed, for example, a desired signal sequence or a functional sequence such as a tag sequence, has been added.

Tat System-Dependent Signal Peptide (Signal Sequence)

[0061] In an embodiment as described herein, the Tat system-dependent signal peptide refers to a signal peptide recognized by the Tat system. The Tat system-dependent signal peptide possesses an arginine-arginine sequence, and by the Tat proteins (or Tat secretion apparatus) recognizing this sequence, it can secrete proteins having this signal peptide at the N-terminus to outside the bacterial body (extracellular).

[0062] A heterologous protein may or may not be linked to the Tat system-dependent signal peptide at their N-terminus. By the heterologous protein having the Tat system-dependent signal peptide at their N-terminus, the Tat system can recognize the arginine-arginine sequence in the signal peptide and can secrete the heterologous protein from inside the bacterial body (intracellular) to outside the bacterial body (extracellular), but the Tat system-dependent signal peptide can be cleaved from the heterologous protein either simultaneously with secretion or thereafter. Therefore, the heterologous protein being produced and secreted may or may not be linked to the Tat system-dependent signal peptide. Preferably, the heterologous protein being produced and secreted are not linked to the Tat system-dependent signal peptide.

[0063] Examples of the Tat system-dependent signal peptide include the signal peptide of Escherichia coli trimethylamine N-oxide reductase (TorA) (SEQ ID NO: 49), the signal peptide of Escherichia coli Sufl (suppressor of ftsl; ftsl suppressor) (SEQ ID NO: 50), the signal peptide of Bacillus subtilis-derived PhoD (phosphodiesterase) (SEQ ID NO: 51), the signal peptide of Streptomyces lividans-derived XInC (xylanase) (SEQ ID NO: 52), the signal peptide of Arthrobacter globiformis-derived isomaltodextranase (IMD) (SEQ ID NO: 53), and other signal peptides, including the signal peptide of Bifidobacterium longum-derived FAD-dependent oxidoreductase (SEQ ID NO: 72).

[0064] Among these, preferably as the Tat system-dependent signal peptides are the signal peptide of trimethylamine N-oxide reductase derived from Escherichia coli (TorA signal peptide, TorAss) and the signal peptide of FAD-dependent oxidoreductase derived from Bifidobacterium longum, with the signal peptide of trimethylamine N-oxide reductase derived from Escherichia coli (TorA signal peptide, TorAss) being more preferable.

[0065] Examples of the amino acid sequences of the signal peptides include amino acid sequences having 70% or more, preferably 80% or more, more preferably 90% or more, further more preferably 95% or more, further more preferably 98% or more, further more preferably 99% or more, and most preferably 100% sequence identity with any of the amino acid sequences of SEQ ID NOs: 49 to 53 and 72 (preferably, the amino acid sequence of SEQ ID NO: 49 being the amino acid sequence of the signal peptide of trimethylamine N-oxide reductase derived from Escherichia coli, or the amino acid sequence of SEQ ID NO: 72 being the amino acid sequence of the signal peptide of FAD-dependent oxidoreductase derived from Bifidobacterium longum).

[0066] As stated above, a heterologous protein may or may not have a part or all of the signal peptide removed by the endogenous or heterologous signal peptidases possessed by the host when secreted extracellularly through the Tat system secretion apparatus (Tat system, Tat pathway). Therefore, the heterologous protein produced and secreted by the bacteria of an embodiment as described herein may be a heterologous protein with the signal peptide completely removed, that is, not retaining any signal peptide (fully cleaved type of a heterologous protein), a heterologous protein with a part of the signal peptide removed (partially cleaved type of a heterologous protein), or a heterologous protein having the signal peptide (uncleaved type of a heterologous protein). Preferably, it is a heterologous protein with the signal peptide completely removed.

Tat Protein

[0067] In an embodiment as described herein, the Tat system refers to the pathway also known as the Twin-arginine translocation pathway, a mechanism or pathway that recognizes a conserved region of arginine-arginine retained in the signal peptide to secrete proteins. Proteins in the Tat system can include TatA, TatB, and TatC. In an embodiment as described herein, the Tat system secretion apparatus refers to membrane proteins constituted by one or more of TatA, TatB, and TatC. TatA, TatB, and TatC are transmembrane proteins existing in the cell membrane, and they are believed to form pores for the translocation of proteins on the cell membrane.

[0068] In an embodiment as described herein, Tat proteins refer to membrane-permeable proteins used in the Tat system. Tat proteins can include TatA, TatB, and TatC.

[0069] TatA is the most abundant component of the Tat complex and is believed to be most involved in the formation of protein transport channels. TatB is known to bind with the Tat system-dependent signal peptide and later play a role in binding with the mature protein. TatC is known to play a role of assisting in binding with the proteins to be transported (Protein J. 2019; 38(4): 377-388).

[0070] The Tat system secretion apparatus exists in a configuration constituted by three kinds of proteins, TatA, TatB, and TatC, or two kinds of proteins, TatA and TatC, depending on the biological species, and in the latter case, it is known that TatA also has the function of TatB. Note that in the latter case, for example, in Bacillus subtilis, proteins equivalent to TatA are known as TatAd and TatAy, and proteins equivalent to TatC are known as TatCd and TatCy. In an embodiment as described herein, TatA is a concept encompassing not only the TatA of various microorganisms but also TatAd and TatAy of Bacillus subtilis. Similarly, TatC is a concept encompassing not only the TatC of various microorganisms but also TatCd and TatCy of Bacillus subtilis.

[0071] The heterologous Tat proteins expressed by the bacteria of an embodiment as described herein preferably include at least one selected from TatA, TatB, and TatC, more preferably include TatA and TatC, and most preferably include TatA, TatB, and TatC.

[0072] In an embodiment as described herein, heterologous Tat protein refers to a Tat protein that is foreign to the bacteria used in an embodiment as described herein. The heterologous protein may be a plant-derived Tat protein, or may be a bacterium-derived Tat protein, but it is preferably a bacterium-derived Tat protein, more preferably a Tat protein derived from bacteria selected from the genus Corynebacterium, the genus Bacillus, and the genus Bifidobacterium, and further more preferably a Tat protein derived from bacteria of the genus Corynebacterium or the genus Bacillus.

[0073] Examples of bacteria of the genus Corynebacterium include Corynebacterium glutamicum, Corynebacterium ammoniagenes, and Corynebacterium casei. Among these, Corynebacterium glutamicum is preferable, and the C. glutamicum 2256 strain is more preferable.

[0074] Bacteria of the genus Bacillus include Bacillus subtilis and Bacillus thuringiensis. Among these, Bacillus subtilis is preferable, and the Bacillus subtilis 168 strain is more preferable.

[0075] Among these, it is preferable to be a Tat protein derived from bacteria of the genus Corynebacterium, and it is more preferable to be a Tat protein derived from Corynebacterium glutamicum.

[0076] The heterologous Tat protein may be a Tat protein having the same amino acid sequence as the natural Tat protein endogenous in the aforementioned organisms, or it may be a modified Tat protein that has altered the amino acid sequence to the extent that it does not impair the function of the Tat protein endogenous in the aforementioned organisms, but it is preferable to be a Tat protein having the same amino acid sequence as the natural Tat protein endogenous in the aforementioned organisms.

[0077] As for TatA, TatB, and TatC proteins, they may be TatA, TatB, and TatC proteins derived from the aforementioned organisms. Among these, it is preferable to be TatA, TatB, and TatC proteins derived from Corynebacterium glutamicum, or TatAd, TatCd, TatAy, and TatCy proteins derived from Bacillus subtilis, or TatA, TatB, and TatC proteins derived from Bifidobacterium longum (preferably from Bifidobacterium longum E-18 strain).

[0078] The TatA protein, TatB protein, and TatC protein derived from Corynebacterium glutamicum have amino acid sequences of SEQ ID NOs: 24, 25, and 26, respectively.

[0079] The TatAd protein, TatCd protein, TatAy protein, and TatCy protein derived from Bacillus subtilis have amino acid sequences of SEQ ID NOs: 39, 40, 41, and 42, respectively.

[0080] The TatA protein, TatB protein, and TatC protein derived from Bifidobacterium longum E-18 strain have amino acid sequences of SEQ ID NOs: 46, 47, and 48, respectively.

[0081] As to the heterologous TatA used in an embodiment as described herein, there are no particular limitations on the amino acid sequence thereof as long as it retains the membrane penetration function possessed by TatA having the amino acid sequence of SEQ ID NO: 24, 39, 41, or 46, but it is preferable to have an amino acid sequence having 70% or more sequence identity with the amino acid sequence of SEQ ID NO: 24, 39, 41, or 46, more preferably have an amino acid sequence having 80% or more sequence identity, further more preferably have an amino acid sequence having 90% or more sequence identity, further more preferably have an amino acid sequence having 95% or more sequence identity, further more preferably have an amino acid sequence having 98% or more sequence identity, further more preferably have an amino acid sequence having 99% or more sequence identity, and further more preferably have an amino acid sequence having 100% sequence identity.

Signal Peptidase

[0084] In an embodiment as described herein, signal peptidase refers to a protein (enzyme) that has the activity to remove part or all of the signal peptide from proteins possessing a Tat system-dependent signal peptide.

[0085] The bacteria of an embodiment as described herein preferably express a signal peptidase that removes part or all (preferably all) of the Tat system-dependent signal peptide from proteins possessing the Tat system-dependent signal peptide.

[0086] As for the signal peptidase, there are no particular limitations as long as it possesses the aforementioned activity, but it is preferable to have four conserved regions, BoxB, BoxC, BoxD, and BoxE, in the amino acid sequence (Pharmacol. Ther. 2000 87: 27-49), more preferable to be type I signal peptidase derived from Escherichia coli (EcLepB; Mol. Gen. Genet. 1991 227; 40-44.), type I signal peptidase derived from Bacillus subtilis (SipS, SipT; Genes Dev. 1998 12; 2318-2331.), type I signal peptidase derived from Corynebacterium glutamicum (C. glutamicum) strain 2256 (CgLepB; WO 2020/085511), type I signal peptidase derived from Lactococcus lactis (L. lactis) strain MG1363 (LlLepB), type I signal peptidase derived from Lactobacillus reuteri (L. reuteri) (LrLepB), type I signal peptidase derived from Bifidobacterium longum (B. longum) (BlLepB), and type I signal peptidase derived from Staphylococcus (S. epidermidis) (SeLepB), with Corynebacterium glutamicum (C. glutamicum) strain 2256-derived type I signal peptidase (CgLepB; WO 2020/085511) and Lactococcus lactis (L. lactis) strain MG1363-derived type I signal peptidase (LlLepB) being particularly preferable.

Other Configurations

[0097] The bacterium of an embodiment as described herein may have an endogenous protease gene that is deficient or has reduced expression. The deficiency or reduction in the expression of the protease gene can prevent the degradation of the protein to be produced and secreted.

Genetic Construct

[0098] In an embodiment as described herein, a genetic construct refers to something that possesses, at appropriate positions where they can function, a promoter, sequences encoding appropriate signal peptides and a nucleic acid fragment encoding the target protein, and control sequences necessary to express the target protein gene (such as operators and terminators).

[0099] The bacterium of an embodiment as described herein preferably contains a genetic construct including a nucleic acid sequence encoding a heterologous protein. Also, it is preferable that the genetic construct includes, in the 5 to 3 direction, a nucleic acid sequence encoding a Tat system-dependent signal peptide and a nucleic acid sequence encoding a heterologous protein. At this time, there is no stop codon between the nucleic acid sequence encoding the Tat system-dependent signal peptide and the nucleic acid sequence encoding the heterologous protein. This allows for the production in the host bacterium of the heterologous protein to which the Tat system-dependent signal peptide is linked at the N-terminus.

[0100] Furthermore, the genetic construct preferably includes a nucleic acid sequence encoding a heterologous Tat protein. The nucleic acid sequence encoding the heterologous Tat protein may be located at the 5-terminus side of the nucleic acid sequence encoding the Tat system-dependent signal peptide, or at the 3-terminus side of the nucleic acid sequence encoding the heterologous protein. Also, the nucleic acid sequence encoding the heterologous Tat protein and the nucleic acid sequence encoding the heterologous protein may exist within the same genetic construct, or they may each exist within different genetic constructs.

Vector

[0101] The bacteria used in an embodiment as described herein preferably contain a recombinant vector in which the genetic construct has been incorporated. Examples of vectors used to incorporate the genetic construct include, but are not limited to, plasmids, transposons, and phages. As for the plasmids, there are no particular limitations as long as it is possible to incorporate the genetic construct in an appropriate arrangement, and various plasmids can be used.

[0102] There are no particular limitations on the method for incorporating the genetic construct or each gene, promoter sequences, or the like contained in the genetic construct into the vector, and for example, it can be incorporated into the vector by connecting the genetic construct to the cleavage site obtained by digesting a specific sequence of the vector with a restriction enzyme.

Nucleic Acid Sequence Encoding Heterologous Tat Protein

[0103] The genetic construct or vector preferably includes a nucleic acid sequence encoding a heterologous Tat protein.

[0104] In an embodiment as described herein, nucleic acid sequence encoding a heterologous Tat protein refers to a nucleic acid sequence encoding a Tat protein that is foreign to the bacteria used in an embodiment as described herein. The aforementioned can be given as examples of heterologous Tat proteins.

[0105] The nucleic acid sequence encoding a heterologous Tat protein preferably includes nucleic acid sequences encoding at least one Tat protein selected from TatA, TatB, and TatC, more preferably includes nucleic acid sequences encoding TatA (tatA) and nucleic acid sequences encoding TatC (tatC), and further more preferably includes nucleic acid sequences encoding TatA (tatA), nucleic acid sequences encoding TatB (tatB), and nucleic acid sequences encoding TatC (tatC).

[0106] As nucleic acid sequences encoding TatA, TatB, and TatC proteins, they may be nucleic acid sequences encoding the aforementioned biologically derived TatA, TatB, and TatC proteins. Among these, it is preferable to be a nucleic acid sequence encoding TatA, TatB, and TatC proteins derived from Corynebacterium glutamicum, or TatAd, TatCd, TatAy, and TatCy proteins derived from Bacillus subtilis, or TatA, TatB, and TatC derived from Bifidobacterium longum (preferably from Bifidobacterium longum E-18 strain).

[0108] The nucleic acid sequences encoding TatAd protein, TatCd protein, TatAy protein, and TatCy protein derived from Bacillus subtilis have nucleic acid sequences of SEQ ID NOs: 35, 36, 37, and 38, respectively.

[0109] The nucleic acid sequences encoding TatA, TatB, and TatC proteins derived from Bifidobacterium longum E-18 have nucleic acid sequences of SEQ ID NOs: 43, 44, and 45, respectively.

[0110] The nucleic acid sequences encoding the TatA, TatB, and TatC proteins used in an embodiment as described herein are preferably nucleic acid sequences having 70% or more (preferably 80% or more, more preferably 90% or more, further more preferably 95% or more, further more preferably 98% or more, further more preferably 99% or more, and most preferably 100%) sequence identity with the above nucleic acid sequences.

[0111] Furthermore, the nucleic acid sequences encoding heterologous TatA, TatB, and TatC may be optimized according to the bacterium to serve as a host (note that it is preferable keep the amino acid sequences of TatA, TatB, and TatC unchanged and optimize the nucleic acid sequences encoding them). For example, it is possible to enhance the translation efficiency of a gene by substituting rare codons present in the gene with synonymous codons used more frequently. That is, the gene to be introduced may be modified to have optimal codons according to the codon usage frequency of the host to be used. Codon substitution can be carried out, for example, by a site-specific mutation method that introduces the target mutation into the target portion of DNA. Also, a gene fragment with substituted codons may be entirely synthesized. The codon usage frequencies in various organisms are disclosed in Codon Usage Database (http://www.kazusa.or.jp/codon; Nakamura, Y. et al, Nucl. Acids Res., 28, 292 (2000)).

[0112] Nucleic acid sequences preferably have 70% or more (preferably 80% or more, more preferably 90% or more, further more preferably 95% or more, further more preferably 98% or more, further more preferably 99% or more, and most preferably 100%) sequence identity with SEQ ID NOs: 15, 16, and 17 in the case of Lactococcus lactis and Lactobacillus reuteri, SEQ ID NOs: 18, 19, 20 in the case of Bifidobacterium longum, and SEQ ID NOs: 21, 22, 23 in the case of Staphylococcus epidermidis, which are optimized from TatA, TatB, and TatC of Corynebacterium glutamicum.

[0113] Moreover, the nucleic acid sequences encoding the heterologous TatA, TatB, and TatC used in an embodiment as described herein preferably have nucleic acid sequences corresponding to the amino acid sequences described in the above section Heterologous Tat Proteins.

[0114] In a genetic construct or vector, the nucleic acid sequence encoding the heterologous Tat proteins may be located on the 5-side of the nucleic acid sequence encoding the Tat system-dependent signal peptide described later, or on the 3-side of the nucleic acid sequence encoding the heterologous protein, but it is preferable to be located on the 5-side.

[0115] Furthermore, in a genetic construct or vector, the nucleic acid sequence encoding heterologous Tat proteins is preferably located on the 3-side of the promoter sequence described later.

The aforementioned can be given as examples of a heterologous protein.

[0136] The nucleic acid sequence encoding a heterologous protein can be optimized according to the host bacterium, or it may not be optimized. Methods for optimizing the nucleic acid sequence according to the host bacterium include, for example, those similar to the methods described in the Nucleic Acid Sequence Encoding Heterologous Tat Protein section.

[0137] It is preferable that the nucleic acid sequence encoding a heterologous protein has, on the 5-terminus side thereof, a nucleic acid sequence encoding the Tat system-dependent signal peptide. Specifically, it is preferable that the genetic construct includes, from the 5 to 3 direction, a nucleic acid sequence encoding the Tat system-dependent signal peptide and a nucleic acid sequence encoding a heterologous protein.

[0138] Additionally, the nucleic acid sequence encoding the Tat system-dependent signal peptide and the nucleic acid sequence encoding a heterologous protein are preferably configured such that there exists no stop codon therebetween, and the heterologous protein is expressed with the N-terminal thereof connected to the signal peptide.

C. under anaerobic conditions using AnaeroPack (registered trademark) (manufactured by Mitsubishi Gas Chemical Company, Inc.). Subsequently, 250 ?L of the resulting culture solution was inoculated into 5 mL of M17 (G10M17) medium containing 10 ?g/mL chloramphenicol, 10 mg/L catalase (derived from bovine liver), 40 g/L calcium carbonate, and 10 g/L glucose, and shake-cultured for 48 hours at 30? C. under anaerobic conditions using AnaeroPack (registered trademark) (manufactured by Mitsubishi Gas Chemical Company, Inc.). Afterward, the resulting culture solution was centrifuged at 7500?g at 4? C. for 10 minutes. The supernatant was filtered, and the filtrate was concentrated using an ultrafiltration filter (Amicon (registered trademark) Ultra 3K, manufactured by Merck), obtaining a culture supernatant concentrate. The resulting culture supernatant concentrate was subjected to reducing SDS-PAGE using NuPAGE 10% Bit-Tris Protein Gels (manufactured by Thermo Fisher Scientific) and NuPAGE MOPS-SDS Runnning buffer (manufactured by Thermo Fisher Scientific). Subsequently, it was transferred to a PVDF membrane using iBlot Gel transfer Stacks PVDF, Mini (manufactured by Thermo Fisher Scientific) and iBlot 2 Dry Blotting System (manufactured by Thermo Fisher Scientific). The transferred PVDF membrane was blotted with anti-FGF2 monoclonal antibody (manufactured by Thermo Fisher Scientific) and Goat anti-mouse IgG (H+L)?HRP conjugate (manufactured by Thermo Fisher Scientific) using iBind Western Systems (manufactured by Thermo Fisher Scientific) and I Bind Flex Solution Kit (manufactured by Thermo Fisher Scientific). After blotting, the PVDF membrane was washed with ultrapure water, immersed in ECL Prime Western Blotting Detection Reagent (manufactured by Cytiva) at room temperature for 5 minutes, and detected with ChemiDoc (manufactured by Bio-Rad).

[0181] Lactococcus lactis MG1363/pNZ9148 strain, Lactococcus lactis MG1363/pNZ9148-CgtatABC strain, Lactococcus lactis MG1363/pNZ9148-torAss-fgf2 strain, Lactococcus lactis MG1363/pNZ9148-CgtatABC-torAss-fgf2 strain, Lactococcus lactis MG1363/pNZ9148-CgtatABC-torAss-fgf2-CglelpB strain, Lactococcus lactis MG1363/pNZ9148-torAss-fgf2-CglepB strain, Lactococcus lactis MG1363/pNZ9148-CgtatABC-torAss-fgf2-LllepB strain, and Lactococcus lactis MG1363/pNZ9148-torAss-fgf2-LllepB strain were scraped with a 10-?L-volume loop, each inoculated into 5 mL of M17 (G5M17) medium containing 10 ?g/mL chloramphenicol and 5 g/L glucose, and shake-cultured for 20 hours at 30?

C. under anaerobic conditions using AnaeroPack (registered trademark) (manufactured by Mitsubishi Gas Chemical Company, Inc.). Afterward, the resulting culture solution was centrifuged at 7500?g at 4? C. for 10 minutes. The supernatant was filtered, and the filtrate was concentrated using an ultrafiltration filter (Amicon (registered trademark) Ultra 3K, manufactured by Merck), obtaining a culture supernatant concentrate. The protein concentration in the resulting culture supernatant concentrate was quantified using the Quick Start Bradford protein assay kit (manufactured by Bio-Rad). The culture supernatant was diluted so that the total protein amount was 12 ?g, and it was subjected to reducing SDS-PAGE using NuPAGE 10% Bit-Tris Protein Gels (manufactured by Thermo Fisher Scientific) and NuPAGE MOPS-SDS Runnning buffer (manufactured by Thermo Fisher Scientific). Subsequently, it was transferred to a PVDF membrane using iBlot Gel transfer Stacks PVDF, Mini (manufactured by Thermo Fisher Scientific) and iBlot 2 Dry Blotting System (manufactured by Thermo Fisher Scientific). The transferred PVDF membrane was blotted with anti-FGF2 monoclonal antibody (manufactured by Thermo Fisher Scientific) and Goat anti-mouse IgG (H+L)?HRP conjugate (manufactured by Thermo Fisher Scientific) using iBind Western Systems (manufactured by Thermo Fisher Scientific) and I Bind Flex Solution Kit (manufactured by Thermo Fisher Scientific).

[0186] Lactococcus lactis MG1363/pNZ9148-torAss-ppghis-LllepB strain and Lactococcus lactis MG1363/pNZ9148-Pusp45-CgtatABC-torAss-ppghis-LllepB strain were scraped with a 1-?L-volume loop, each inoculated into 5 mL of M17 (G5M17) medium containing 10 ?g/mL chloramphenicol and 5 g/L glucose, and shake-cultured for 20 hours at 30? C. under anaerobic conditions using AnaeroPack (registered trademark) (manufactured by Mitsubishi Gas Chemical Company, Inc.). Subsequently, 100 ?L of the resulting culture solution was inoculated into 5 mL of M17 (G10M17) medium containing 10 ?g/mL chloramphenicol, 10 mg/L catalase (derived from bovine liver), 40 g/L calcium carbonate, and 10 g/L glucose, and shake-cultured for 48 hours at 30? C. under anaerobic conditions using AnaeroPack (registered trademark) (manufactured by Mitsubishi Gas Chemical Company, Inc.). Afterward, the resulting culture solution was centrifuged at 7500?g at 4? C. for 10 minutes. The supernatant was filtered, and the filtrate was concentrated using an ultrafiltration filter (Amicon (registered trademark) Ultra 3K, manufactured by Merck), obtaining a culture supernatant concentrate. The protein concentration in the resulting culture supernatant concentrate was quantified using the Quick Start Bradford protein assay kit (manufactured by Bio-Rad). The culture supernatant was diluted so that the total protein amount was 18 ?g, and it was subjected to reducing SDS-PAGE in the same method as in <2-6>. Subsequently, it was transferred to a PVDF membrane in the same method as in <2-6>, and was blotted with a 6x-His tag monoclonal antibody (His.

After blotting, the PVDF membrane was washed with ultrapure water, immersed in ECL Prime Western Blotting Detection Reagent (manufactured by Cytiva) at room temperature for 5 minutes, and detected with ChemiDoc (manufactured by Bio-Rad). The molecular weights were estimated using the software Quantity One (manufactured by Bio-rad).

[0187] The results are shown in FIG. 3. A band was detected only in Lactococcus lactis MG1363/pNZ9148-Pusp45-CgtatABC-torAss-ppghis-LllepB strain, around 33.5 kDa, which is the estimated molecular weight of Pro-PGHisx6. Additionally, no band was detected around 43.3 kDa, which is the molecular weight of the induction protein TorAss-Pro-PGHisx6 with the signal sequence uncut. Therefore, it has been demonstrated that the enhancement of signal peptidase I derived from Lactococcus lactis and the heterologous expression of the Tat system secretion apparatus derived from Corynebacterium glutamicum leads to the secretion of Pro-PGHisx6 with the signal sequence removed.

C. under anaerobic conditions using AnaeroPack (registered trademark) (manufactured by Mitsubishi Gas Chemical Company, Inc.). Afterward, the resulting culture solution was centrifuged at 7500?g at 4? C. for 10 minutes. The supernatant was filtered, and the filtrate was concentrated using an ultrafiltration filter (Amicon (registered trademark) Ultra 3K, manufactured by Merck), obtaining a culture supernatant concentrate. The resulting culture supernatant concentrate was subjected to Western blotting in the same manner as <1-6>.
