The chemical structure of the K14-antigenic polysaccharide (K14 antigen) of Escherichia coli 06:K14:H31 was elucidated by determination of the composition, 1H- and 13C-n.m.r. spectroscopy, periodate oxidation, and study of the oligosaccharides obtained by partial hydrolysis. The polysaccharide consists of [O-(2-acetamido-2-deoxy-β-d-galactopyranosyl)-(1→5)-O- (3-deoxy-β-d-manno-octulopyranosylonic acid)-(2→6)] repeating units, ∼60% of the octonic acid units being O-acetylated and ∼10% O-propionylated at O-8. The sequence of acetylated and propionylated residues is not known. The serologically-specific part of the K14 antigen resides in the polysaccharide part.
