Structural comparison of the O6 specific polysaccharides from E. coli O6:K2:H1, E. coli O6:K13:H1, and E. coli O6:K54:H10.
Two distinct forms of the O6 antigen (LPS) from E. coli were analysed using 1H and 13C NMR spectroscopy. Their structures were found to be [formula: see text] In the O6-specific polysaccharide from E. coli O6:K2 and O6:K13, X is beta-D-Glc p, as had previously been shown for the O6 polysaccharide from E. coli O6:K15; in the O6 specific polysaccharide from E. coli O6:K54, X is beta-D-Glc pNAc.
