oligosaccharyltransferase

oligosaccharyltransferase
ol·i·go·sac·cha·ryl·trans·fer·ase (ol″ĭ-go-sak″ə-ril-transґfər-ās) an enzyme of the transferase class that catalyzes the transfer of the assembled oligosaccharide precursor from the dolichol phosphate carrier to the asparagine residue of a polypeptide chain in N-linked glycosylation. In EC nomenclature called dolichyl-diphosphooligosaccharide–protein glycotransferase.
