DE   undecaprenyl-diphosphooligosaccharide--protein glycotransferase.
CA   tritrans,heptacis-undecaprenyl diphosphooligosaccharide + [protein]-L-
CA   asparagine = tritrans,heptacis-undecaprenyl diphosphate + a glycoprotein
CA   with the oligosaccharide chain attached by N-beta-D-glycosyl linkage to
CA   protein L-asparagine.
CC   -!- A bacterial enzyme that has been isolated from Campylobacter jejuni
CC       and Campylobacter lari.
CC   -!- It forms a glycoprotein by the transfer of a glucosyl-N-
CC       acetylgalactosaminyl-N,N'-diacetylbacillosamine
CC       (GalNAc2(Glc)GalNAc3diNAcBac) polysaccharide and related
CC       oligosaccharides to the side-chain of an L-asparagine residue in the
CC       sequence -Asp/Glu-Xaa-Asn-Xaa'-Ser/Thr- (Xaa and Xaa' not Pro) in
CC       nascent polypeptide chains.
CC   -!- Occurs on the external face of the plasma membrane.
CC   -!- The polyprenol involved is normally tritrans,heptacis-undecaprenol
CC       but a decaprenol is used by some species.
