2.4.99.21	dolichyl phosphooligosaccharide + [flagellum protein FlaB2]-L-asparagine101	the enzyme participates in the N-linked glycosylation in Methanococcus voltae. It catalyzes transfer of oligosaccharides from the dolichyl phosphate donor to asparagine in the acceptor proteins. The activity is dependent on the canonical AsnXaaSer/Thr sequon. Although the full length N-glycan generated by Methanococcus voltae (L-threonyl 2-(acetylamino)-2-deoxy-beta-D-mannuronamido-(1->4)-2,3-bis(acetylamino)-2,3-bis(acetylamino)-2,3-dideoxy-beta-D-glucuronosyl-(1->3)-2-(acetylamino)-2-deoxy-beta-D-glucosyl-[protein]-L-asparagine) is a trisaccharide, the disaccharide-linked substrate is sufficient for oligosaccharyl transferase activity
