Accepted name: UDP-N-acetylglucosamine—decaprenyl-phosphate N-acetylglucosaminephosphotransferase
Reaction: UDP-N-acetyl-α-D-glucosamine + trans,octacis-decaprenyl phosphate = UMP + N-acetyl-α-D-glucosaminyl-diphospho-trans,octacis-decaprenol

Other name(s): GlcNAc-1-phosphate transferase; UDP-GlcNAc:undecaprenyl phosphate GlcNAc-1-phosphate transferase; WecA; WecA transferase
Systematic name: UDP-N-acetyl-α-D-glucosamine:trans,octacis-decaprenyl-phosphate N-acetylglucosaminephosphotransferase
Comments: Isolated from Mycobacterium tuberculosis and Mycobacterium smegmatis. This enzyme catalyses the synthesis of monotrans,octacis-decaprenyl-N-acetyl-α-D-glucosaminyl diphosphate (mycobacterial lipid I), an essential lipid intermediate for the biosynthesis of various bacterial cell envelope components. cf. EC, UDP-GlcNAc:undecaprenyl-phosphate GlcNAc-1-phosphate transferase.
