Vorschrift
An enzyme solution (0.1 ml) is added to 0.3 ml of 100 mM phosphate buffer (pH 7.8) containing 0.1 ml of 1% N-acetyl-D-glucosamine as a substrate, and the resultant mixture is incubated at 37° C. for 30 minutes. The amount of D-glucosamine formed is determined colorimetrically using indole-HCl according to the method of Z. Dische and E. Borenfreund [J. Biol. Chem., 184:517 (1950)]. One unit of the enzyme is defined as the amount of the enzyme which is capable of producing 1 μmol D-glucosamine from N-acetyl-D-glucosamine per minute at 37° C.
