ABSTRACT

The O-specific polysaccharide was isolated from the lipopolysaccharide of Rheinheimera pacifica KMM 1406T and studied by chemical methods along with 1H and 13C NMR spectroscopy. It was shown that the polysaccharide contains one residue each of 2-cetamido-2-deoxy-D-galactose (D-GalNAc), 2-acetamido-2-deoxy-D- and 2-acetamido-2-deoxy-L-galacturonic acids (D-GalNAcA, L-GalNAcA), 2,4-diacetamido-2,4,6-trideoxy-D-glucose (D-QuiNAc4NAc), and 4-(N-acetyl-D-alanyl)amino-4,6-dideoxy-D-glucose (D-Qui
4NAlaAc) and has the following structure :
