| Accepted name: |
UDP-N-acetylglucosamine—lysosomal-enzyme N-acetylglucosaminephosphotransferase |

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. |
