Anionic polymers of the cell surface of a thermophilic streptomycete were investigated. The cell wall of Streptomyces thermoviolaceus subsp. thermoviolaceus VKM Ac-1857^T was found to contain polymers with different structure: teichoic acid - 1,3-poly(glycerol phosphate), disaccharide-1-phosphate polymer with repeating unit -6)-alpha-Galp-(1→6)-alpha-GlcpNAc-P-, and polysaccharide without phosphate with repeating unit →6)-alpha-GalpNAc-(1→3)-beta-GalpNAc-(1→. Disaccharide-1-phosphate and polysaccharide without phosphate have not been described earlier in prokaryotic cell walls.
