  • N-acetylglucosamine-2-epimerase and method for producing CMP-neuraminic acid using the same
    Patent number: 8852891
    Abstract: The present invention relates to a novel N-acetylglucosamine-2-epimerase and a method for preparing CMP-N-acetylneuraminic acid, more specifically, relates to a N-acetylglucosamine-2-epimerase derived from Bacteroides fragilis NCTC 9343, and a method for preparing CMP-N-acetylneuraminic acid using said N-acetylglucosamine-2-epimerase. According to the present invention, CMP-N-acetylneuraminic acid can be produced economically in a large amount through a one-step reaction using cytidine monophosphate and N-acetyl-D-glucosamine which are inexpensive substrates.
