undecaprenyl-diphosphooligosaccharide-protein glycotransferase

A bacterial enzyme that has been isolated from Campylobacter jejuni and Campylobacter lari. It forms a glycoprotein by the transfer of a glucosyl-N-acetylgalactosaminyl-N,N'-diacetylbacillosamine (GalNAc2(Glc)GalNAc3diNAcBac) polysaccharide and related oligosaccharides to the side-chain of an L-asparagine residue in the sequence -Asp/Glu-Xaa-Asn-Xaa'-Ser/Thr- (Xaa and Xaa' not Pro) in nascent polypeptide chains. Requires Mn2+ or Mg2+. Occurs on the external face of the plasma membrane. The polyprenol involved is normally tritrans,heptacis-undecaprenol but a decaprenol is used by some species.
