ID 1.1.1.240 DE N-acetylhexosamine 1-dehydrogenase. CA N-acetyl-alpha-D-glucosamine + NAD(+) + H2O = N-acetyl-D-glucosaminate + CA NADH + 2 H(+). CC -!- Also acts on N-acetylgalactosamine and, more slowly, CC on N-acetylmannosamine. CC -!- Anomeric specificity was tested with N-acetyl-D-glucosamine, and it CC was shown that the enzyme is specific for the alpha anomer. //
