Accepted name:
UDP-N-acetylbacillosamine N-acetyltransferase
Other names:
UDP-4-amino-4,6-dideoxy-N-acetyl-α-D-glucosamine N-acetyltransferase
pglD (gene name)

acetyl-CoA:UDP-4-amino-4,6-dideoxy-N-acetyl-α-D-glucosamine N-acetyltransferase



The product, UDP-N,N'-diacetylbacillosamine, is an intermediate in protein glycosylation pathways in several bacterial species, including N-linked glycosylation of certain L-asparagine residues in Campylobacter species [1,2] and O-linked glycosylation of certain L-serine residues in Neisseria species [3].
