Undecaprenyl-diphosphooligosaccharide-protein glycotransferase

Undecaprenyl-diphosphooligosaccharide-protein glycotransferase (, PglB) is an enzyme with systematic name . This enzyme catalyses the following chemical reaction


 * + [protein]-L-asparagine $$\rightleftharpoons$$ + 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.
