[The structure of a repetitive unit of the glycerolphosphate- containing O-specific polysaccharide chain from Yersinia kristensenii strain 103 (0:12,26) lipopolysaccharide].

Mild acid hydrolysis of the lipopolysaccharide from Yersinia kristensenii strain 103 (0:12.26) afforded teichoic acid-like polysaccharide. From the results of methylation, dephosphorylation, partial Smyth degradation, and 13C and 31P NMR data the structure of the repeating unit of the polysaccharide was deduced as follows: [formula: see text] The structure was confirmed by complete interpretation of polysaccharide 13C NMR spectrum.
