On the structure of the teichoic acid from the cell wall of Streptomyces antibioticus 39. Localization of the phosphodiester linkages and elucidation of the monomeric units structure by means of 13C-nuclear-magnetic-resonance spectroscopy.

The cell walls of Streptomyces antibioticus 39 contain a glycosylated poly(glycerol phosphate), in which the repeating monomeric unit is O-alpha-D-galactopyranosyl-(1--3)-O-2-acetamido-2-deoxy-beta-D-galactopyranosyl-(1--1)-glycerol monophosphate. The localization of the phosphodiester linkages between hydroxyl groups at positions 2 and 3 of the adjacent glycerol residues and the structure of the glycoside were established by 13C nuclear-magnetic-resonance spectroscopy. The spectral data are also in accordance with the results of the methylation analysis and enzyme degradation of the glycoside.
