Structural studies on the O-specific side-chain polysaccharide of lipopolysaccharide from the Yersinia pseudotuberculosis VA serovar.

The polysaccharide of the O-specific side chain of the lipopolysaccharide from the Yersinia pseudotuberculosis VA serovar has been isolated and studied. The structural pattern of the chemical repeating unit of the specific polysaccharide has been proposed as follows: (formula; see text).
