Abstract
The structures of the 6-deoxytalose-containing O-specific polysacchari des from the O45 antigen, an O45-related antigen (O45rel), and the O66 antigen (lipopolysaccharides, LPSs) of Escherichia coli were elucidat ed by chemical characterization and by one- and two-dimensional H-1 an d C-13 NMR Spectroscopy. The O45 and O45-related polysaccharides have the following general structure. [GRAPHICS] For the O45 antigen, X is alpha-D-Fuc pNAc and for the O45-related antigen, X is beta-D-Glc pNAc . The structure of the O66 polysaccharide is [GRAPHICS] CS]
