Abstract
An N-acetylhexosamine oxidase having the following physiochemical properties. (1) Action and specificity for substrate Oxidizes N-acetylhexosamine in the presence of oxygen to form N-acetylhexosaminic acid and hydrogen peroxide. Hardly acts or does not act at all on hexose and hexosamine. (2) Optimum pH and stable pH range When a potassium phosphate buffer solution contining 0.1M glycine is used, an optimum pH is 7.5 to 8.5 and a stable pH range is 3 to 9. (3) Molecular weight Has a molecular weight of about 140,000 to 150,000 when measured according to a gel filtration method using Sephadex G-200 by the use of 0.05M potassium phosphate buffer solution.
