The subject of the present review is the structural diversity and abundance of cell wall teichuronic and teichulosonic acids of representatives of the order Actinomycetales. Recently found teichulosonic acids are a new class of natural glycopolymers with ald-2-ulosonic acid residues: Kdn (3-deoxy-D-glycero-D-galacto-non-2-ulosonic acid) or di-N-acyl(More)
Anionic polymers of the cell surface of a thermophilic streptomycete were investigated. The cell wall of Streptomyces thermoviolaceus subsp. thermoviolaceus VKM Ac-1857T was found to contain polymers with different structure: teichoic acid — 1,3-poly(glycerol phosphate), disaccharide-1-phosphate polymer with repeating unit-6)-α-Galp-(1→6)-α-GlcpNAc-P-, and(More)
Anionic phosphate-containing cell wall polymers of bacilli are represented by teichoic acids and poly(glycosyl 1-phosphates). Different locations of phosphodiester bonds in the main chain of teichoic acids as well as the nature and combination of the constituent structural elements underlie their structural diversity. Currently, the structures of teichoic(More)
Cell walls of Bacillus subtilis VKM B-760 and VKM B-764 are characterized by heterogeneous composition of teichoic acids. Polymer I with structure -6)-β-D-Galp-(1→1)-sn-Gro-(3-P-, polymer II with structure -6)-α-D-Glcp-(1→1)-sn-Gro-(3-P-, and a small amount of unsubstituted 1,3-poly(glycerol phosphate) were detected in strain VKM B-760. Strain VKM B-764(More)
A comparative study of the structures of carbohydrate-containing cell wall polymers isolated from the strains of the Bacillus subtilis group was performed by means of chemical and NMR spectroscopic meth ods. Polymers of different structure were revealed, namely, 1,3-poly(glycerol phosphates) with β-glucopyranose in Bacillus subtilis strains VKM B-520, VKM(More)
The type strains of the species of the cluster “Streptomyces lavendulae” with a low level of DNA–DNA relatedness were found to contain different cell-wall carbohydrate polymers, whereas the species of this cluster with a level of DNA–DNA relatedness of about 60% contain similar or identical carbohydrate polymers. The type strains Streptomyces katraeVKM(More)
The teichoic acids (TAs) of type strains, viz. Bacillus licheniformis VKM B-511T and Bacillus pumilus VKM B-508T, as well as phylogenetically close bacteria VKM B-424, VKM B-1554, and VKM B-711 previously assigned to Bacillus pumilus on the basis of morphological, physiological, and biochemical properties, were investigated. Three polymers were found in the(More)
The cell wall anionic polymers of the 13 species of the “Streptomyces cyaneus” cluster have a similar structure and contain β-glucosylated 1,5-poly(ribitol phosphate) and 1,3-poly(glycerol phosphate). In the degree of glucosylation of the ribitol phosphate units of their teichoic acids, the cluster members can be divided into two groups. The streptomycetes(More)
The cell wall of Actinoplanes utahensis VKM Ac-674T contains two anionic polymers: teichoic acid 1,3-poly(glycerol phosphate) that is widespread in cell walls of Gram-positive bacteria; and a unique teichulosonic acid belonging to a new class of bioglycans described only in microorganisms of the Actinomycetales order. The latter polymer contains residues of(More)
The structure of cell wall teichoic acids was studied by chemical methods and NMR spectroscopy in the type strains of two actinomycete species of the “Streptomyces griseoviridis” phenetic cluster: streptomyces daghestanicus and streptomyces murinus. S. daghestanicus VKM Ac-1722t contained two polymers having a 1,5-poly(ribitol phosphate) structure. In one(More)
