IntEnz Enzyme Nomenclature


Accepted name:
UDP-N-acetylglucosamine—lysosomal-enzyme N-acetylglucosaminephosphotransferase
Other names:
N-acetylglucosaminyl phosphotransferase
UDP-N-acetylglucosamine:glycoprotein N-acetylglucosamine-1-phosphotransferase
UDP-N-acetylglucosamine:glycoprotein N-acetylglucosaminyl-1-phosphotransferase
UDP-N-acetylglucosamine:lysosomal enzyme N-acetylglucosamine-1-phosphotransferase
UDP-GlcNAc:glycoprotein N-acetylglucosamine-1-phosphotransferase
lysosomal enzyme precursor acetylglucosamine-1-phosphotransferase
Systematic name:
UDP-N-acetyl-D-glucosamine:lysosomal-enzyme N-acetylglucosaminephosphotransferase



Some other glycoproteins with high-mannose can act as acceptors, but much more slowly than lysosomal enzymes.
