Abstract
N-Acetylmannosamine dehydrogenase which takes off hydrogen from N-acetylmannosamine to convert it into N-acetylmannosaminolactone and, at the same time, reduces coenzyme NAD into NADH. This enzyme can be obtained by culturing, in a medium, a strain belonging to Genus Flavobacterium and having an ability to produce N-acetylmannosamine dehydrogenase producing activity, and then collecting it. This enzyme is usable in the quantitative analysis of N-acetylmannosamine or sialic acid.
