A neutral polysaccharide was obtained by hot phenol-water extraction of biomass from Campylobacter jejuni 176.83 and subsequently separated from acid-liberated core oligosaccharide of lipopolysaccharide by sequential GPC on Bio-Gel P6 and TSK-40 columns. All sugar components of the trisaccharide repeating unit of the polysaccharide were found to be of the furanose ring form. The major trisaccharide contained β-L-arabinose, 6-deoxy-β-D-altro-heptose (β-D-6d-altHep) and 6-deoxy-β-L-altrose (β-L-6d-Alt), whereas in the minor trisaccharide the β-L-6d-Alt is replaced by its C-5 epimer α-D-Fuc. On the basis of 1H and 13C NMR spectroscopic studies, including 2D ROESY, HMQC and HMQC-TOCSY experiments, the following structures of the repeating units were established: [formula: see text]
Methods: NMR-2D, NMR, acid hydrolysis Comments, role: major repeating unit of the polysaccharide has the structure: -2)bLAraf(1-2)bD6daltHepf(1-2)bL6dAltf(1- (75%) and minor repeating unit has the structure: -2)bLAraf(1-2)bD6daltHepf(1-2)aDFucf(1- (25%)
