R12100 ]
Reaction(KEGG)
Substrate
UDP-alpha-D-glucuronate [CPD:
C00167 ];
archaeal dolichyl alpha-D-glucosyl phosphate [CPD:
C22506 ]
Product
UDP [CPD:
C00015 ];
archaeal dolichyl beta-D-glucuronosyl-(1->4)-alpha-D-glucosyl phosphate [CPD:
C21902 ]
Comment
The enzyme, characterized from the halophilic archaeon Haloferax volcanii, participates in the protein N-glycosylation pathway. Dolichol used by archaea is different from that used by eukaryotes. It is much shorter (C55-C60) and is alpha,omega-saturated. However, in vitro the enzyme was also able to act on a substrate with an unsaturated end.
