UDP-4-amino-4,6-dideoxy-N-acetyl-beta-L-altrosamine N-acetyltransferase Sequences in this family are members of the pfam00583 (GNAT) superfamily of acetyltransferases and are proposed to perform a N-acetylation step in the process of pseudaminic acid biosynthesis in Campylobacter species. This gene is commonly observed in apparent operons with other genes responsible for the biosynthesis of pseudaminic acid and as a component of flagellar and exopolysaccharide biosynthesis loci. Significantly, many genomes containing other components of this pathway lack this gene, indicating that some other N-acetyl transferases may be incolved and/or the step is optional, resulting in a non-acetylated pseudaminic acid variant sugar. |
