Novel thermostable collagen-digesting enzyme, novel microorganism producing the enzyme and process for producing the enzyme |
摘要 |
Bacillus sp. NTAP-1 having been deposited under accession number FERM BP-6926; and a collagen-decomposing enzyme produced by bacterium. The above enzyme (1) has a capability of hydrolyzing, at the highest efficiency, collagen and gelatin from among casein, gelatin, albumin and collagen; (2) shows the optimum pH of 3.5 to 4.5; (3) shows the optimum temperature of 65 to 70 DEG C; (4) after heating at 60 DEG C at pH 6.0 for 4 hours, sustains an activity amounting to 60% or more of the level before the heat treatment; (5) remains stable at pH 3 to 6; and a molecular weight of approximately 46,000 when measured by SDS-PAGE. |
