Structure of a teichoic acid-like O-polysaccharide of Escherichia coli O29.
A teichoic acid-like O-polysaccharide was isolated by mild acid degradation of the lipopolysaccharide (LPS) of Escherichia coli O29. The O-polysaccharide and an oligosaccharide obtained by dephosphorylation of the O-polysaccharide were studied by sugar analysis along with 1H and 13C NMR spectroscopy. The following structure of the branched oligosaccharide repeating unit, containing five monosaccharide residues and glycerol 1-phosphate (D-Gro-1-P), was established: [carbohydrate structure: see text].
