Reaction: UDP-N-acetyl-D-glucosamine + lysosomal-enzyme D-mannose = UMP + lysosomal-enzyme N-acetyl-D-glucosaminyl-phospho-D-mannose
Other name(s): N-acetylglucosaminylphosphotransferase; UDP-N-acetylglucosamine:lysosomal enzyme N-acetylglucosamine-1-phosphotransferase; UDP-GlcNAc:glycoprotein N-acetylglucosamine-1-phosphotransferase; uridine diphosphoacetylglucosamine-lysosomal enzyme precursor acetylglucosamine-1-phosphotransferase; uridine diphosphoacetylglucosamine-glycoprotein acetylglucosamine-1-phosphotransferase; lysosomal enzyme precursor acetylglucosamine-1-phosphotransferase; N-acetylglucosaminyl phosphotransferase; UDP-acetylglucosamine:lysosomal enzyme N-acetylglucosamine-1-phosphotransferase; UDP-GlcNAc:lysosomal enzyme N-acetylglucosamine-1-phosphotransferase; UDP-N-acetylglucosamine:glycoprotein N-acetylglucosamine-1-phosphotransferase; UDP-N-acetylglucosamine:glycoprotein N-acetylglucosaminyl-1-phosphotransferase
Systematic name: UDP-N-acetyl-D-glucosamine:lysosomal-enzyme N-acetylglucosaminephosphotransferase
Comments: Some other glycoproteins with high-mannose can act as acceptors, but much more slowly than lysosomal enzymes.
