IntEnz Enzyme Nomenclature


Accepted name:
UDP-N-acetylglucosamine—dolichyl-phosphate N-acetylglucosaminyltransferase
Other names:
UDP-N-acetylglucosamine-dolichol phosphate N-acetylglucosaminyltransferase
dolichyl-phosphate α-N-acetylglucosaminyltransferase
dolichyl-phosphate acetylglucosaminyltransferase
uridine diphosphoacetylglucosamine-dolichol phosphate acetylglucosaminyltransferase
aglK (gene name)
UDP-N-acetyl-D-glucosamine:dolichyl-phosphate α-N-acetyl-D-glucosaminyltransferase
Systematic name:
UDP-N-acetyl-α-D-glucosamine:dolichyl-phosphate α-N-acetyl-D-glucosaminyltransferase



The enzyme, characterized from the methanogenic archaeon Methanococcus voltae, initiates N-linked glycosylation in that organism. The enzyme differs from the eukaryotic enzyme, which leaves one additional phosphate group on the dolichyl product (cf. EC, UDP-N-acetylglucosamine—dolichyl-phosphate N-acetylglucosaminephosphotransferase).
