Structure of the K10 capsular antigen from Escherichia coli O11:K10:H10, a polysaccharide containing 4,6-dideoxy-4-malonylamino-D-glucose.
The K10 antigen from Escherichia coli O11:K10:H10 consists of equimolar amounts of rhamnose and 4,6-dideoxy-4-malonylaminoglucose [Qui4NMal; 4-(2-carboxyacetamido)-4,6-dideoxyglucose]. Methylation analysis and 1 and 2D NMR spectroscopy showed that the K10 capsular polysaccharide has the structure [formula: see text]
