General Information | Comment | Organism |
---|---|---|
metabolism | a general N-linked glycosylation pathway, encoded by the pgl gene cluster, culminates in the transfer of a heptasaccharide: GalNAc-alpha1,4-GalNAc-alpha1,4-(Glcalpha1,3)-GalNAc-alpha1,4-GalNAc-alpha1,4-GalNAc-alpha1,3-Bac, where Bac is bacillosamine, i.e. 2,4-diacetamido-2,4,6-trideoxyglucose, from a membrane-anchored undecaprenylpyrophosphate (Und-PP)-linked donor to the asparagine side chain of proteins at the Asn-X-Ser/Thr motif. For biosynthesis of Und-PP-linked heptasaccharide, PglA and PglJ add the first two GalNAc residues on to the isoprenoid-linked Bac carrier, respectively. Elongation of the trisaccharide with PglH results in a hexasaccharide revealing the polymerase activity of PglH. The final branching glucose is then added by PglI, which prefers native lipids for optimal activity. Pathway overview | Campylobacter jejuni |
