Structure of the O83-specific polysaccharide of Escherichia coli O83:K24:H31.
The polysaccharide moiety of the O83 antigen (lipopolysaccharide, LPS) consists of D-glucose, D-galactose, 2-acetamido-2-deoxy-D-glucose, and D-glucuronic acid in the molar ratios 1:2:1:1. Methylation analysis of the polysaccharide and derived oligosaccharides as well as one- and two-dimensional 1H and 13C NMR spectroscopy of the polysaccharide at pD 1 and 6 showed that the O83 polysaccharide has the primary structure-->6)-alpha-D-Glc p-(1-->4)-beta-D-Glc pA-(1-->6)-beta-D-Gal p-(1-->4)-beta-D- Gal p-(1-->4)-beta-D-Glc pNAc-(1-->.
