- Аннотация: The cell wall of endophytic strain Rathayibacter oskolensis VKM Ac-2121T (family Microbacteriaceae, class Actinomycetes) was found to contain neutral and acidic glycopolymers. The neutral polymer is a block-type rhamnomannan partially should be substitutied by xylose residues, [→2)-α-[β-D-Xylp-(1→3)]-D-Manp-(1→3)-α-D-Rhap-(1→]~30 [→2)-α-D-Manp-(1→3)-α-D-Rhap-(1→]~45. The acidic polymer has branched chain, bearing lactate and pyruvate residues, →4)-α-D-[S-Lac-(2―3)-α-L-Rhap-(1→3)]-D-Manp-(1→3)-α-D-[4,6-R-Pyr]-D-Galp-(1→3)-β-D-Glcp-(1→. The structures of both glycopolymers were not described in the Gram-positive bacteria to date. The glycopolymers were studied by chemical and NMR spectroscopic methods. The results of this study provide new data on diversity of bacterial glycopolymers and may prove useful in the taxonomy of the genus Rathayibacter and for understanding the molecular mechanisms of interaction between plants and plant endophytes.
