Structure of the O-specific polysaccharide from a marine bacterium Cellulophaga tyrosinoxydans

The O-polysaccharide was isolated from the lipopolysaccharide of Cellulophaga tyrosinoxydans and studied by chemical analyses along with 1H and 13C NMR spectroscopy, including 2D 1H, 1H COSY, TOCSY, ROESY, 1Н, 13С HSQC, HMBC and H2BC experiments. The following new structure of the O-polysaccharide o...

Description
Summary:The O-polysaccharide was isolated from the lipopolysaccharide of Cellulophaga tyrosinoxydans and studied by chemical analyses along with 1H and 13C NMR spectroscopy, including 2D 1H, 1H COSY, TOCSY, ROESY, 1Н, 13С HSQC, HMBC and H2BC experiments. The following new structure of the O-polysaccharide of C. tyrosinoxydans containing l-fucose (Fuc), N-acetyl-d-glucosamine (GlcNAc), 4-acetamido-4,6-dideoxy-d-glucose (Qui4NAc) and two l-rhamnose residues (Rha) was established:▪. [Display omitted] •The O-polysaccharide was isolated from a marine bacterium Cellulophaga tyrosinoxydans.•Structure of the polysaccharide was established by NMR and chemical approaches.•The polysaccharide is built up of branched pentasaccharide repeating units.
