Abstract

The O-polysaccharide was isolated from the lipopolysaccharide of Echinicola pacifica KMM 6172(T) and studied by chemical analyses along with (1)H and (13)C NMR spectroscopy, including (1)H, (1)H COSY, 1D and 2D TOCSY, ROESY, (1)H, (13)С HMQC, HMBC and H2BC experiments. It was found that the polysaccharide is built up of branched pentasaccharide repeating units, containing D-galactose (Gal), L-rhamnose (Rha), 2-acetamido-2-deoxy-D-glucose (GlcNAc), two residues of 2,3-diacetamido-2,3-dideoxy-D-glucuronic acid (GlcNAc3NAcA) and O-acetyl group in nonstoichiometric amount and has the following structure [Structure: see text].
