Реферат: Structure of the Acinetobacter baumannii strain MAR22-3311 classified to KL205 type capsular polysaccharide (CPS) was established by component analyses, Smith degradation as well as 1H and 13C NMR spectroscopy, including two-dimensional homonuclear 1Н,1Н COSY, TOCSY, ROESY and heteronuclear 1Н,13C HSQC and HMBC experiments. The K205 CPS is composed of branched hexasaccharide K-units containing three d-GalNAc residues, and one residue each of d-Quip3NAc, d-Galp and d-Glcp. The following structure of the hexasaccharide repeating unit of the CPS was established. Functions of genes in the K locus of A. baumannii MAR22-3311 (K205) were assigned by a comparison with sequences in the available databases and found to be in agreement with the CPS structure.
