Subspecies : jejuni
Strain : NCTC 11168 serotype O:2
Taxonomic ID (NCBI) 192222
Genome Information
GenBank AL111168.1
EMBL AL111168
Organism Additional Information Campylobacter jejuni is a microaerophilic, Gram-negative, human pathogen that is the major cause of bacterial food-borne diarrhoea (gastroenteritis). It is most frequently responsible for a form of post-infection neuromuscular paralysis known as Guillain Barre' syndrome. It also leads to an immunoproliferative small intestine disease that is a rare malignant lymphoma of the intestine. Motility is essential for pathogenicity.

Glycan Information
Glycan Annotation Linkage: Bac-Asn.
1406 Da heptasaccharide composed of GalNAc-α1,4-GalNAc-α1,4-[Glcβ1,3-]GalNAc-α1,4-GalNAc-α1,4-GalNAc-α1,3-Bac-β1,N-Asn-Xaa, where Bac is bacillosamine, 2,4-diacetamido-2,4,6-trideoxyglucopyranose.
BCSDB ID 23625
GlyTouCan G58528CE
Technique(s) used for Glycan Identification 1H, 13C NMR spectroscopy- one dimensional TOCSY (total correlation spectroscopy) and NOESY (nuclear Overhauser effect spectroscopy); HMBC (heteronuclear multiple bond coherence), HMQC (heteronuclear multiple quantum correlation) spectra.
Protein Glycosylation linked (PGL) gene(s)
OST Gene NamePglB
Characterized Accessory Gene(s)PglA, PglJ, PglH, PglI, PglC are glycosyltransferases involved in the heptasaccharide assembly. PglFED are the bacillosamine biosynthetic enzymes. PglK is a flippase.
Accessory Gene(s)Progt IDProGT10.1, ProGT10.2, Pro
Additional CommentSequon feature: The consensus sequence for the C jejuni PglB is D/E-X'-N-X"-S/T (where X' and X" stand for any amino acid except proline) which is glycosylated when located in flexible, exposed structural elements. Tripeptide sequence NLT too has been found to be modified in vitro.
