โฆ Synopsis
Two distinct forms of the 06 antigen (LPS) from E. coli were analysed using 'H and 13C NMR spectroseopoy. Their structures were found to be + 4)-P-D-Mang-( 1 + ~)-LY-D-G~c~NAc-( 1 + 4)-cy-p-GalpNAc-( 1 + 3)-p-~-Manp -( 1 + : X
In the 06-specific polysaccharide from E. coli 06 : K2 and 06 : K13, X is P-D-Glcp, as had previously been shown for the 06 polysaccharide from E. coli 06 : K15; in the 06 specific polysaccharide from E. coli 06:K54, X is P-D-GlcpNAc,

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 of the K54-antigenic polysaccharide (K54 antigen) of Escherichia coli O6:K54:H10 was elucidated by determination of the composition, 1H- and 13C-n.m.r. spectroscopy, periodate oxidation, and a study of the oligosaccharides obtained by partial hydrolysis with acid. The K54 polysaccharid
