The acidic polysaccharide (K6) antigen from Escherichia coli LP 1092 contains d-ribose and 3-deoxy-d-manno-octulosonic acid in the molar ratio of 2:1, respectively. Spectroscopic data (13C- and 1H-n.m.r.), methylation analyses, and periodate oxidation indicate that the polysaccharide is composed of the foregoing components essentially in the following trisaccharide sequence: →2)-β-d-Ribf-(1→2)-β-d-Ribf-(1→7)-α-d-KDO-(2→. The polysaccharide also contains O-acetyl substituents (∼0.2-0.3 mol per KDO residue).
