IntEnz Enzyme Nomenclature


Accepted name:
α-1,3-mannosyl-glycoprotein 4-β-N-acetylglucosaminyltransferase
Other names:
N-acetylglucosaminyltransferase IV
N-glycosyl-oligosaccharide-glycoprotein N-acetylglucosaminyltransferase IV
α-1,3-mannosylglycoprotein β-1,4-N-acetylglucosaminyltransferase
β-acetylglucosaminyltransferase IV
uridine diphosphoacetylglucosamine-glycopeptide β4-acetylglucosaminyltransferase IV
Systematic name:
UDP-N-acetyl-D-glucosamine:3-[2-(N-acetyl-β-D-glucosaminyl)-α-D-mannosyl]-glycoprotein 4-β-N-acetyl-D-glucosaminyltransferase



R represents the remainder of the N-linked oligosaccharide in the glycoprotein acceptor. The best acceptor for this enzyme is probably the same as that favored by EC, β-1,4-mannosyl-glycoprotein 4-β-N-acetylglucosaminyltransferase.
