The structure of the capsular polysaccharide from Klebsiella K43.
The structure of the capsular polysaccharide from Klebsiella type K43 has been investigated using sugar and methylation analysis, uronic acid degradation, and NMR spectroscopy on the native and the O-deacetylated polysaccharide. It is concluded that the polysaccharide is composed of pentasaccharide repeating units with the structure [formula: see text] The polysaccharide contains approximately 0.4 equiv of O-acetyl group per repeating unit, located at a primary position.
