Structural determination of the O-deacetylated O-chain of lipopolysaccharide from Burkholderia (Pseudomonas) cepacia strain PVFi-5A.
On the basis of chemical degradation methods and one-and two-dimensional 1H and 13C NMR experiments the novel following structure was established for the O-deacetylated repeating unit of the O-chain of the main Burkholderia (Pseudomonas) cepacia (strain PVFi-5A) lipopolysaccharide: -->4)-beta-D-GalpNAc-(1-->3)-alpha-D-Galp-(1-->6)-alpha-D-GlcpNAc-(1-->.
