The yeast WBP1 is essential for oligosaccharyl transferase activity in vivo and in vitro.

The EMBO journal - 1 Jun 1992

Abstract excerpt

Asparagine-linked N-glycosylation is a highly conserved and functionally important modification of proteins in eukaryotic cells. The central step in this process is a cotranslational transfer of lipid-linked core oligosaccharides to selected Asn-X-Ser/Thr-sequences of nascent polypeptide chains, catalysed by the enzyme N-oligosaccharyl transferase. In this report we show that the essential yeast protein WBP1 (te...
