Oligosaccharyl transferase (OT) catalyzes the co-translational transfer of a dolichol-linked tetradecasaccharide (Dol-PP-GlcNAc(2)Man(9)Glc(3), 1a) to an asparagine side chain of a nascent polypeptide inside the lumen of the endoplasmic reticulum (ER). The glycosyl acceptor requires an Asn-Xaa-Thr/Ser sequon, where Xaa can be any natural amino acid except proline, for N-linked glycosylation to occur. To address the substrate specificity of the glycosyl donor, three unnatural dolichol-linked… CONTINUE READING
