Dolichyl-phosphooligosaccharide-protein glycotransferase 3

UniProtKB accession:  O29867

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Oligosaccharyl transferase (OST) that catalyzes the initial transfer of a defined glycan (a glucose-linked heptasaccharide composed of 3 Glc, 2 Man, 2 Gal and a sulfate for A.fulgidus AglB-L) from the lipid carrier dolichol-monophosphate to an asparagine residue within an Asn-X-Ser/Thr consensus motif in nascent polypeptide chains, the first step in protein N-glycosylation.
