Accepted name: UDP-N-acetylgalactosamine-undecaprenyl-phosphate N-acetylgalactosaminephosphotransferase
Reaction: UDP-N-acetyl-α-D-galactosamine + ditrans,octacis-undecaprenyl phosphate = UMP + N-acetyl-α-D-galactosaminyl-diphospho-ditrans,octacis-undecaprenol
Other name(s): WecP; UDP-GalNAc:polyprenol-P GalNAc-1-P transferase; UDP-GalNAc:undecaprenyl-phosphate GalNAc-1-phosphate transferase
Systematic name: UDP-N-acetyl-α-D-galactosamine:ditrans,octacis-undecaprenyl phosphate N-acetyl-D-galactosaminephosphotransferase
Comments: The enzyme catalyses a step in the assembly of the repeating-unit of the O-antigen of the Gram-negative bacterium Aeromonas hydrophila AH-3. The enzyme shows no activity with UDP-N-acetyl-α-D-glucosamine (cf. EC, UDP-N-acetylglucosamine-undecaprenyl-phosphate N-acetylglucosaminephosphotransferase).
