Structure elucidation of the O-chain from the major lipopolysaccharide of the Xanthomonas campestris strain 642

Structure elucidation of the O-chain from the major lipopolysaccharide of the Xanthomonas campestris strain 642

A novel O-polysaccharide consisting of d-Xyl p and l-Rha p in the molar ratio of 1:2.5 was identified as the major component in the lipopolysaccharide fraction of Xanthomonas campestris strain 642, which is responsible for a new bacterial disease of the strawberry plant. Its structure was mainly det...

Zusammenfassung:A novel O-polysaccharide consisting of d-Xyl p and l-Rha p in the molar ratio of 1:2.5 was identified as the major component in the lipopolysaccharide fraction of Xanthomonas campestris strain 642, which is responsible for a new bacterial disease of the strawberry plant. Its structure was mainly determined using chemical analysis, Smith degradation and 1D and 2D NMR spectroscopy experiments as:
