The capsular polysaccharide (K98 antigen) of E. coli O7:K98:H6 contains rhamnose, glucuronic acid, and acetate in the molar ratios 3:1:0.6. Methylation analysis, oligosaccharide analysis, and 1D- and 2D-n.m.r. spectroscopy revealed the polysaccharide to be a glucuronic acid-substituted rhamnan with the structure [formula; see text] Of the 3-linked rhamnose residues, approximately 60% are O-acetylated at position 2.
