The structure of the K54-antigenic polysaccharide (K54 antigen) of Escherichia coli O6:K54:H10 was elucidated by determination of the composition, 1H- and 13C-n.m.r. spectroscopy, periodate oxidation, and a study of the oligosaccharides obtained by partial hydrolysis with acid. The K54 polysaccharide consists of →3)-β-D-glucosyluronic acid-(1→3)-α-L-rhamnosyl-(1→ repeating-units. Of the glucuronic acid residues, approximately 85% are substituted in the ratio 9:1 with L-threonine and L-serine amidically linked to the carboxyl group. The K54 polysaccharide has a molecular weight of approximately 160,000, corresponding to approximately 380 repeating-units.
