UDP-4-amino-4,6-dideoxy-N-acetyl-alpha-D-glucosamine N-acetyltransferase

UDP-4-amino-4,6-dideoxy-N-acetyl-alpha-D-glucosamine N-acetyltransferase (EC 2.3.1.203, PGLD) is an enzyme with systematic name acetyl-CoA:UDP-4-amino-4,6-dideoxy-N-acetyl-alpha-D-glucosamine N-acetyltransferase.^[1]^[2]^[3] This enzyme catalyses the following chemical reaction

acetyl-CoA + UDP-4-amino-4,6-dideoxy-N-acetyl-alpha-D-glucosamine

\rightleftharpoons

CoA + UDP-N,N'-diacetylbacillosamine

UDP-N,N'-diacetylbacillosamine is an intermediate in protein glycosylation pathways in several bacterial species.
