NMR spectroscopy was performed on the depyruvated capsular antigen of E. coli K103 and on the oligosaccharide obtained by depolymerisation of the native polysaccharide with a viral-borne endoglycanase. This capsular polysaccharide is the only one to be co-expressed with O group 101 and joins a small group of unusual capsular polysaccharides which possess pyruvic acid as the only acidic function. The primary structure was shown to be composed of the repeating unit: .
capsular polysaccharide, NMR spectroscopy, pyruvate, E. coli, Bacteriophage depolymerization
Structure type: polymer chemical repeating unit
