Structure of the O-specific polysaccharide containing pentitol phosphate, isolated from Hafnia alvei strain PCM 1191 lipopolysaccharide.
The O-specific polysaccharide of the lipopolysaccharide produced by Hafnia alvei strain PCM 1191 was shown by composition and methylation analyses, periodate oxidation and one- and two-dimensional 1H- and 31P-NMR spectroscopy to be a polymer of a branched hexasaccharide repeating units having the structure: [formula: see text] where LAraol = L-arabitol The polysaccharide of 1191 strain has teichoic-acid-like character. Its peculiar feature is the presence of arabitol phosphate, a component observed for the first time in bacterial lipopolysaccharides.
