title: Anionic polymers of the cell wall of Bacillus subtilis subsp. subtilis VKM B-501(T).
abstract: Teichoic acid and disaccharide-1-phosphate polymer were identified in the cell walls of Bacillus subtilis subsp. subtilis VKM B-501(T). The teichoic acid represents 1,3-poly(glycerol phosphate) 80% substituted by alpha-D-glucopyranose residues at O-2 of glycerol. The linear repeating unit of disaccharide-1-phosphate polymer contains the residues of beta-D-glucopyranose, N-acetyl-alpha-D-galactosamine, and phosphate and has the following structure: -6)-beta-D-Glcp-(1-->3)-alpha-D-GalpNAc-(1-P-. The structures of two anionic polymers were determined by chemical and NMR-spectroscopic methods. The 1H- and 13C-NMR spectral data on disaccharide-1-phosphate polymer are presented for the first time.
