Structure of the repeating unit of the O-specific polysaccharide of the lipopolysaccharide of Yersinia kristensenii strain 490 (O:12,25)

The O-specific polysaccharide isolated by mild acid degradation of the lipopolysaccharide of Y. kristensenii strain 490 (O:12,25) contained D-glucose, 2-acetamido-2-deoxy-D-glucose, 2-acetamido-2-deoxy-D-galactose, 2-acetamido-2,6-dideoxy-L-galactose, glycerol, and phosphate in the ratios 2:2:1:1:1:...

Summary:The O-specific polysaccharide isolated by mild acid degradation of the lipopolysaccharide of Y. kristensenii strain 490 (O:12,25) contained D-glucose, 2-acetamido-2-deoxy-D-glucose, 2-acetamido-2-deoxy-D-galactose, 2-acetamido-2,6-dideoxy-L-galactose, glycerol, and phosphate in the ratios 2:2:1:1:1:1. On the basis of 31P- and 13C-n.m.r. data, methylation analysis, dephosphorylation, solvolysis with anhydrous hydrogen fluoride, and Smith degradation, it was concluded that the repeating unit of the polysaccharide was a branched hexaosylglycerol phosphate with the following structure.
