Structure of the O-specific polysaccharide of the lipopolysaccharide of Rahnella aquatilis 95 U003

The O-polysaccharide of Rahnella aquatilis 95 U003 was obtained by mild acid degradation of the lipopolysaccharide and studied by sugar and methylation analyses, Smith degradation and 1H and 13C NMR spectroscopy, including 2D 1H,1H COSY, TOCSY, ROESY, H-detected 1H,13C HSQC and HMQC-TOCSY experiments. The O-polysaccharide was found to have a branched hexasaccharide repeating unit of the following structure:Figure optionsDownload full-size imageDownload as PowerPoint slide
