[Structure of an acidic polysaccharide found in a bacteriolytic complex of lysoamidase].
A structural study of an acidic polysaccharide, a component of the lysoamidase bacteriolytic complex has been carried out. Analysis of the monosaccharide composition of the original polysaccharide, of the product of carboxyl groups reduction and of the 13C-NMR and 1H-NMR spectra of the original and the O-deacetylated polysaccharides using two-dimensional NMR spectroscopy has made it possible to establish the structure of the repeating trisaccharide unit of the polysaccharide as follows: [formula: see text] where ManNAcA and GalNAcA are 2-acetamido-2-deoxymannuronic acid and 2-acetamido-2-deoxygalacturonic acid, respectively. Also small amount of a neutral polysaccharide containing of rhamnose is present in the lysoamidase preparation.
