title: Structure of the O-specific polysaccharide of the marine bacterium Arenibacter palladensis KMM 3961(T) containing 2-acetamido-2-deoxy-l-galacturonic acid.
abstract: The O-specific polysaccharide was obtained by mild acid degradation of the lipopolysaccharide of the marine bacterium Arenibacter palladensis type strain KMM 3961(T) and studied by chemical methods and (1)H and (13)C NMR spectroscopy including 2D COSY, TOCSY, (1)H,(13)C HSQC, and HMBC experiments. The polysaccharide was shown to consist of tetrasaccharide repeating units containing two mannose residues (Man), one 2-acetamido-2-deoxy-D-galactose residue (D-GalNAc), and one 2-acetamido-2-deoxy-L-galacturonic acid residue (L-GalNAcA) and having the following structure: →2)-α-D-Manp-(1→6)-α-D-Manp-(1→4)-α-L-GalpNAcA-(1→3)-β-D-GalpNAc-(1→.
