Dolichyl-diphosphooligosaccharide–protein glycosyltransferase 48 kDa subunit is an enzyme that in humans is encoded by the DDOST gene.This gene encodes a component of the oligosaccharyltransferase complex which catalyzes the transfer of high-mannose oligosaccharides to asparagine residues on nascent polypeptides in the lumen of the rough endoplasmic reticulum. The protein complex co-purifies with ribosomes.
