NOVEL KERATINASE DERIVED FROM THERMOPHILIC BACTERIA AND USE THEREOF

摘要

The present invention relates to thermophile-derived novel keratinase having keratin decomposition ability. In addition, 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, comprising a step of culturing the host cells. Additionally, the present invention relates to: a composition for decomposing keratin, containing the enzyme; and a method for decomposing keratin by using the same. In addition, the present invention relates to a decomposed product of keratin 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.
