Abstract
The present invention provides a novel protein having N-acetylglucosamine 2-epimerase activity; a DNA encoding the protein; a recombinant vector containing the DNA; a transformant obtainable by introducing the recombinant vector into a host cell; and a process for producing the protein or N-acetylmannosamine using the transformant.
Claims10
A protein selected from the following proteins (a) and (b):
- (a) a protein comprising the amino acid sequence represented by SEQ ID NO:1, and
- (b) a protein comprising an amino acid sequence wherein at least one amino acid is deleted, replaced or added in the amino acid sequence of the protein (a), and having N-acetylglucosamine 2-epimerase activity.
A DNA selected from the following DNAs (a) and (b):
- (a) a DNA comprising the nucleotide sequence represented by SEQ ID NO:2, and
- (b) a DNA which hybridizes with the DNA (a) under the stringent conditions and which encodes a protein having N-acetylglucosamine 2-epimerase activity.
