ProteomicsOligosaccharyltransferase is involved in targeting to ER-associated degradation
The majority of secretory proteins undergo N-glycosylation, a process catalyzed by oligosaccharyltransferase (OST), a membrane-bound protein complex that associates with the translocation channels within the endoplasmic reticulum (ER). Proteins failing quality control undergo ER-associated degradati...

ProteomicsAnalysis of the substrate specificities and reaction kinetics of the yeast oligosaccharyltransferase isoforms
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...
