title: Carbohydrate-containing polymers of the cell wall of the thermophilic streptomycete Streptomyces thermoviolaceus subsp. thermoviolaceus VKM Ac-1857T.
abstract: 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.
