Abstract/OtherAbstract:
|
Cell walls of each of five bacterial strains belonging to the genus Kribbella (family Nocardioidaceae, order Actinomycetales) contain a neutral polysaccharide (mannan) and teichulosonic acid of novel structure in different proportions. The novel teichulosonic acid found in strains VKM Ac-2500, VKM Ас-2568, VKM Ас-2572, and VKM Ас-2575 is a heteropolymer with an irregular structure where fragments I (predominant) alternate with fragments II (minor): The teichulosonic acid from Kribbella sp. VKM Ac-2527 has in general a structure similar to that above with the exception that the Pse residue is randomly glycosylated at O-4 with β-l-Rhap (along with α-d-Galp3OMe or α-d-Galp2,3OMe). The strain VKM Ac-2572 contained additionally teichuronic acid with the disaccharide repeating unit consisted of aminomannuronic acid and 2,3-diacetamido-2,3-dideoxy-α-glucopyranose. The mannan, a polysaccharide common to all of the strains, is built of (1→6)-linked α-d-mannopyranose substituted with α-d-mannopyranose at O-2. The structures of all the glycopolymers were established by a combination of chemical and NMR spectroscopic methods. |
