Abstract—

A phosphorylated O-specific polysaccharide was obtained by mild acidic degradation of the lipopolysaccharide from the enteric bacterium Escherichia coli O130 and characterized by the methods of chemical analysis, including dephosphorylation and 1H and 13C NMR spectroscopy. The polysaccharide was shown to be composed of branched tetrasaccharide repeating units containing two N-acetyl-D-galactosamine residues, D-galactose, D-glucose, and glycerophosphate residues (one of each). The polysaccharide has the following structure, which is unique among the known bacterial polysaccharides:
