Sysname
UDP-4-amino-4,6-dideoxy-N-acetyl-alpha-D-glucosamine:2-oxoglutarate aminotransferase
Reaction(IUBMB)
UDP-4-amino-4,6-dideoxy-N-acetyl-alpha-D-glucosamine + 2-oxoglutarate = UDP-2-acetamido-2,6-dideoxy-alpha-D-xylo-hex-4-ulose + L-glutamate [RN:R04529]
Reaction(KEGG)
Substrate
UDP-4-amino-4,6-dideoxy-N-acetyl-alpha-D-glucosamine;
2-oxoglutarate [CPD:C00026]
Product
UDP-2-acetamido-2,6-dideoxy-alpha-D-xylo-hex-4-ulose [CPD:C04613];
L-glutamate [CPD:C00025]
Comment
A pyridoxal-phosphate protein. The enzyme is involved in biosynthesis of UDP-N,N-diacetylbacillosamine, an intermediate in protein glycosylation pathways in several bacterial species, including N-linked glycosylation of certain L-aspargine residues in Campylobacter species [1-3] and O-linked glycosylation of certain L-serine residues in Neisseria species [4].
