IUBMB Enzyme Nomenclature


Accepted name: UDP-galactose—UDP-N-acetylglucosamine galactose phosphotransferase

Reaction: UDP-α-D-galactose + UDP-N-acetyl-α-D-glucosamine = UMP + UDP-N-acetyl-6-(α-D-galactose-1-phospho)-α-D-glucosamine

Other names: uridine diphosphogalactose-uridine diphosphoacetylglucosamine galactose-1-phosphotransferase; galactose-1-phosphotransferase; galactosyl phosphotransferase; UDP-galactose:UDP-N-acetyl-D-glucosamine galactose phosphotransferase

Systematic name: UDP-α-D-galactose:UDP-N-acetyl-D-glucosamine galactose phosphotransferase

Comments: N-Acetylglucosamine end-groups in glycoproteins can also act as acceptors.
