Structural elucidation of the O-chain of the lipopolysaccharide from Xanthomonas campestris strain 8004.
A novel O-specific polysaccharide containing 3-acetamido-3-deoxy-alpha-D-fucose (Fuc3NAc) and D-rhamnose was isolated from the phenol-soluble lipopolysaccharide fraction of the plant associated bacterium Xanthomonas campestris strain 8004. The structure, determined by means of chemical analysis and 1D and 2D NMR spectroscopy, showed a branched trisaccharide repeating unit, as shown below: [formula: see text].
