Oligosaccharyltransferase (OST) catalyzes the central step in N-linked protein glycosylation, the transfer of a pre-assembled oligosaccharide from its lipid carrier onto asparagine residues of secretory proteins. The prototypic hetero-octameric OST complex from the yeast Saccharomyces cerevisiae exi...
