<p> This entry represents a family of aminotransferases involved in the biosynthesis of pseudaminic acid [<cite idref="PUB00040745"/>, <cite idref="PUB00045366"/>, <cite idref="PUB00045367"/>]. They convert UDP-4-keto-6-deoxy-N-acetylglucosamine into UDP-4-amino-4,6-dideoxy-N-acetylgalactose. Pseudaminic acid has a role in surface polysaccharide in Pseudomonas as well as in the modification of flagellin in Campylobacter and Helicobacter species [<cite idref="PUB00045365"/>]. </p> Pseudaminic acid biosynthesis, PseC
