Undecaprenyl-diphosphooligosaccharide-protein glycotransferase (EC 2.4.99.19, PglB) is an enzyme with systematic name tritrans,heptacis-undecaprenyl-diphosphooligosaccharide:protein-L-asparagine N-beta-D-oligosaccharidotransferase.[1][2] This enzyme catalyses the following chemical reaction

tritrans,heptacis-undecaprenyl diphosphooligosaccharide + [protein]-L-asparagine tritrans,heptacis-undecaprenyl diphosphate + a glycoprotein with the oligosaccharide chain attached by N-beta-D-glycosyl linkage to protein L-asparagine

This is a bacterial enzyme that is isolated from Campylobacter jejuni and Campylobacter lari.
