Phosphate-containing polymers of cell wall of bacilli
Biochemistry (Moscow) 76(7) (2011) 745-754
 

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 acids of bacilli can be classified into three types, viz. poly(polyol phosphates) with glycerol or ribitol as the polyol; poly(glycosylpolyol phosphates), mainly glycerol-containing polymers; and poly(acylglycosylglycerol phosphate), in which the components are covalently linked through glycosidic, phosphodiester, and amide bonds. In addition to teichoic acids, poly(glycosyl 1-phosphates) with mono- and disaccharide residues in the repeating units have been detected in cell walls of several Bacillus subtilis and Bacillus pumilus strains. The known structures of teichoic acids and poly(glycosyl 1-phosphates) of B. subtilis, B. atrophaeus, B. licheniformis, B. pumilus, B. stearothermophilus, B. coagulans, B. cereus as well as oligomers that link the polymers to peptidoglycan are surveyed. The reported data on the structures of phosphate-containing polymers of different strains of B. subtilis suggest heterogeneity of the species and may be of interest for the taxonomy of bacilli to allow differentiation of closely related organisms according to the 'structures and composition of cell wall polymers' criterion.

Anionic polymers in cell walls of Gram-positive bacteria
Biochemistry (Moscow) 62(8) (1997) 809-840
 

Information on the prevalence, compositions, and structures of anionic carbohydrate-containing polymers of cell walls of Gram-positive bacteria is summarized. The data suggest that these polymers are important for normal functioning of bacterial cells and require further studies. Structural data on teichoic acids found in the literature published over the last few years are discussed. This is a very diverse class of polymers whose structure-specific pathways of degradation were studied and NMR spectra were examined. Unique comprehensive tables of 13C-NMR spectroscopic data (mainly obtained by the authors) on these polymers are given in the Appendix. Other tables summarize data on teichuronic acids, sugar-phosphate polymers, acid polysaccharides, and structural variants of bonds between acid polysaccharides and peptidoglycans known from the literature. Functions of anionic polymers and their possible chemotaxonomic applications are discussed
