Structure of an acidic polysaccharide present in the bacteriolytic complex lysoamidase.
The structure of an acidic polysaccharide component of a bacteriolytic complex (lysoamidase), isolated from a bacterium of the genus Xanthomonas, was studied. On the basis of sugar analysis and one- and two-dimensional 1H and 13C NMR spectroscopic study of the initial polysaccharide and its O-deacetylated and carboxyl-reduced derivatives, the following structure of the trisaccharide repeating unit of the polysaccharide was established [formula: see text] where ManNAcA and GalNAcA are 2-acetamido-2-deoxymannuronic acid and 2-acetamido-2-deoxygalacturonic acid, respectively.
