BRITE hierarchy
Sysname
UDP-N-acetyl-alpha-D-glucosamine:dolichyl-phosphate alpha-N-acetyl-D-glucosaminyltransferase
Reaction(IUBMB)
UDP-N-acetyl-alpha-D-glucosamine + dolichyl phosphate = UDP + dolichyl N-acetyl-alpha-D-glucosaminyl phosphate [RN:R01008]
Reaction(KEGG)
Substrate
UDP-N-acetyl-alpha-D-glucosamine [CPD:C00043];
dolichyl phosphate [CPD:C00110]
Product
UDP [CPD:C00015];
dolichyl N-acetyl-alpha-D-glucosaminyl phosphate [CPD:C04678]
Comment
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 2.7.8.15, UDP-N-acetylglucosamine---dolichyl-phosphate N-acetylglucosaminephosphotransferase).
