EC 2.4.1.335     
Accepted name: dolichyl N-acetyl-α-D-glucosaminyl phosphate 3-β-D-2,3-diacetamido-2,3-dideoxy-β-D-glucuronosyltransferase
Reaction: UDP-2,3-diacetamido-2,3-dideoxy-α-D-glucuronate + an archaeal dolichyl N-acetyl-α-D-glucosaminyl phosphate = UDP + an archaeal dolichyl 3-O-(2,3-diacetamido-2,3-dideoxy-β-D-glucuronsyl)-N-acetyl-α-D-glucosaminyl phosphate
Other name(s): AglC; UDP-Glc-2,3-diNAcA glycosyltransferase
Systematic name: UDP-2,3-diacetamido-2,3-dideoxy-α-D-glucuronate:dolichyl N-acetyl-α-D-glucosaminyl-phosphate 3-β-D-2,3-diacetamido-2,3-dideoxy-β-D-glucuronosyltransferase
Comments: The enzyme, characterized from the methanogenic archaeon Methanococcus voltae, participates in the N-glycosylation of proteins. Dolichol used by archaea is different from that used by eukaryotes. It is much shorter (C55-C60), it is α,ω-saturated and it may have additional unsaturated positions in the chain.
