Dolichyl-phosphooligosaccharide-protein glycotransferase 2

UniProtKB accession:  O30195

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Oligosaccharyl transferase (OST) that catalyzes the initial transfer of a defined glycan (a GalNAc-linked heptasaccharide composed of 4 Hex, 3 dHex and a sulfate for A.fulgidus AglB-S) 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.
