General Information

General Information Comment Organism
metabolism the Pgl pathway produces the N-linked glycan heptasaccharide GalNAc-alpha1,4-GalNAc-alpha1,4-(Glcbeta1,3)-GalNAc-alpha1,4-GalNAc-alpha1,4-GalNAc-alpha1,3-Bac2,4diNAc-_1-Asn. The pathway begins with diphosphate bond formation between the Bac2,4diNAc phosphate and undecaprenylphosphate (Und-P) by Cj1124c (PglC) to form Bac2,4diNAc-alpha1-PP-Und. One N-acetylgalactosamine is linked to the polyisoprenediphosphate-bound N,N'-diacetylbacillosamine by Cj1125c (PglA) to form GalNAc-alpha1,3-Bac2,4diNAc-alpha1-PP-Und. Next, four additional GalNAc and one branching glucose are added sequentially to the isoprene-linked disaccharide by PglJ, PglH, and PglI, to form the heptasaccharide, overview Campylobacter jejuni
