Accepted name: UDP-N-acetylglucosamine—dolichyl-phosphate N-acetylglucosaminyltransferase
Reaction: UDP-N-acetyl-α-D-glucosamine + dolichyl phosphate = UDP + dolichyl N-acetyl-α-D-glucosaminyl phosphate
Other name(s): aglK (gene name); dolichyl-phosphate α-N-acetylglucosaminyltransferase; 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
Comments: 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).
