General Information | Comment | Organism |
---|---|---|
metabolism | PglI is part of a general N-linked glycosylation pathway, encoded by the pgl gene cluster, which culminates in the transfer of a heptasaccharide: GalNAc-alpha1,4-GalNAc-alpha1,4-(Glcbeta1,3)-GalNAc-alpha1,4-GalNAc-alpha1,4-GalNAc-alpha1,3-Bac, where Bac is bacillosamine (2,4-diacetamido-2,4,6-trideoxyglucose), from a membrane-anchored undecaprenyldiphosphate-linked donor to the asparagine side chain of proteins at the Asn-X-Ser/Thr motif. The glycosyltransferases, PglA, PglH, PglI, and PglJ, responsible for the biosynthesis of the undecaprenyl diphoshate-linked heptasaccharide. The final branching glucose is added by PglI, and the flippase, WlaB, then flips the completed lipid-linked heptasaccharide into the periplasm | Campylobacter jejuni |
