Method: X-ray diffraction, Resolution 1.3Å Ligands: EDO, PG4 Resources: FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT Function OST6_YEAST Essential subunit of the N-oligosaccharyl transferase (OST) complex which catalyzes the transfer of a high mannose oligosaccharide from a lipid-linked oligosaccharide donor to an asparagine residue within an Asn-X-Ser/Thr consensus motif in nascent polypeptide chains. Can participate in redox reactions and is able to catalyze dithiol-disulfide exchange reactions with other proteins, albeit with relatively low efficiency. May form transient disulfide bonds with nascent polypeptides in the endoplasmic reticulum and thereby promote efficient glycosylation. N-glycosylation occurs cotranslationally and the complex associates with the Sec61 complex at the channel-forming translocon complex that mediates protein translocation across the endoplasmic reticulum (ER). All subunits are required for a maximal oligosaccharyl transferase activity. Evolutionary Conservation Check, as determined by ConSurfDB.
