lipid-linked oligosaccharide + unfolded nascent polypeptide chain Saccharomyces cerevisiae N-glycosylation of eukaryotic secretory and membrane-bound proteins is an essential and highly conserved protein modification. The key step in this pathway is the en bloc transfer of the high mannose core oligosaccharide Gly3Man9GlcNAc2 from the lipid carries dolichyl phosphate to selected Asn-X-Ser/Thr sequences of nascent polypeptide chains during their translocation across the endoplasmic reticulum membrane ?
