dolichyl-diphosphooligosaccharide-protein glycotransferase activity
dolichyl-diphosphooligosaccharide-protein glycotransferase activity
Catalysis of the reaction: dolichyl diphosphooligosaccharide + protein L-asparagine = dolichyl diphosphate + a glycoprotein with the oligosaccharide chain attached by glycosylamine linkage to protein L-asparagine.
