ID 1.1.1.240 DE N-acetylhexosamine 1-dehydrogenase. CA H2O + N-acetyl-alpha-D-glucosamine + NAD(+) = 2 H(+) + N-acetyl-D- CA glucosaminate + NADH. 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. //
