Studies on glucosaminidase. 6. N-Acetyl-β-glucosaminidase and N-acetyl-β-galactosaminidase activities of a variety of enzyme preparations

Abstract

The N-acetylglucosamini-dase and N-acetylgalactosaminidase activities of a wide variety of enzyme preparations have been measured. Where N-acetylglucosaminidase was detected it was accompanied by N-acetylgalactosaminidase but the ratios of the activities covered a wide range. Experiments with mixed substrates did not indicate a specific site for either activity in any of the preparations.
