The present invention relates to a novel thermophile-derived keratinase having keratin decomposition ability. Further, the present invention relates to a polynucleotide encoding the keratinase, a recombinant vector containing the same, host cells transformed by using the recombinant vector, and a method for preparing a keratinase including a step of culturing the host cells. Further, the present invention relates to a composition for decomposing keratin containing the enzyme; and a method for decomposing keratin by using the same. Further, the present invention relates to a keratin decomposed product decomposed by the enzyme.

The keratinase according to the present invention rapidly and effectively decomposes hardly-decomposable keratin, and thus it is expected that the keratinase can be used for the effective treatment and the high value-added resource recovery of agricultural and livestock waste, which causes environmental problems (for example, a novel material for enzyme cosmetics), and can be used in an innovative enzymatic bioconversion technique utilizing various decomposition enzyme groups.

Provided is an enzymatic process for preparing mercaptans from disulfides.

A method and a mineral wool product include a multiple of lamellae, such as a sandwich panel core. The product includes a plurality of lamellae cut from a mineral wool web, and bonded together by applying an adhesive on the surfaces of two adjacent lamellae to form a web-like product, wherein the adhesive comprises at least one hydrocolloid.

Antibodies that include a sulfatase motif-containing tag in a constant region of an immunoglobulin (Ig) light chain polypeptide are disclosed. The sulfatase motif can be converted by a formylglycine-generating enzyme (FGE) to produce a formylglycine (fGly)-modified Ig light chain polypeptide. An fGly-modified Ig light chain polypeptide of the antibody can be covalently and site-specifically bound to a moiety of interest to provide an antibody conjugate. The disclosure also encompasses methods of production of such tagged Ig light chain polypeptides, fGly-modified Ig light chain polypeptides, and antibody conjugates, as well as methods of use of same.

The present invention provides compositions for attenuating the function of atypical CYS HIS rich thioredoxin 4 (ACHT4), a light-regulated protein expressed in plants and algae that controls starch storage in chloroplast, and methods for increasing plant and algae growth and yield.

Compositions and methods to produce maize with improved nutritional content are disclosed.

Methods and fluid compositions are provided for decreasing an amount of sulfur-containing compounds in downhole fluids and/or subterranean reservoir wellbores by including at least one enzyme destabilizer in a fluid composition. The fluid composition may then be circulated into a subterranean reservoir wellbore. The fluid composition may further include a base fluid and at least one sulfur producing enzyme. The base fluid may be or include, but is not limited to, drilling fluids, servicing fluids, production fluids, completion fluids, injection fluids, refinery fluids, and combinations thereof. The enzyme destabilizer(s) may be destabilize the sulfur producing enzymes and thereby decrease an amount of sulfur-containing compounds produced vis-à-vis the sulfur producing enzyme(s).

A method of producing lipids, containing the steps of: culturing an alga in which expression of a gene encoding a protein containing a thioredoxin domain and a thioredoxin reductase domain is enhanced, and producing fatty acids or lipids containing the same as components.

The present invention relates to a modified TXNIP protein, a method for preparing the modified TXNIP protein, a polynucleotide encoding the modified protein, an expression vector including the polynucleotide, a transformant introduced with the expression vector, a method for crystallizing a modified TRX-TXNIP complex using the modified TXNIP protein, and a method for screening a substance regulating interaction between TRX and TXNIP, an inhibitor of TRX activity, or a substance regulating TXNIP function.

The present invention concerns in general novel fusion proteins comprising a membrane transferring moiety and an enzymatic moiety. The present invention further concerns a method of treating disease using said fusion proteins.
