摘要:
A keratan sulfate hydrolase of an endo-.beta.-N-acetylglucosaminidase type, obtained by culturing Bacillus circulans such as Bacillus circulans KsT202, has reactivity on keratan polysulfate at high concentrations, an optimum pH of 4.5-6, stability at a pH of 6-7, an optimum temperature of 50.degree.-60.degree. C., thermostability at a temperature of 45.degree. C., and a molecular weight of approximately 200,000 dalton.
