Structural features of cell wall teichoic acid and peptidoglycan of Actinomadura cremea INA 292.
The teichoic acid from the cell wall of Actinomadura cremea INA 292 has an unusual structure, being a poly(galactosylglycerol phosphate) chain with glycerol phosphate groups. Monomeric units of 1-O, beta-D-galactopyranosylglycerol monophosphate are joined in the polymer by phosphodiester links involving the glycerol C3 and the galactose C6 atoms. Approximately every second galactosyl substituent has a glycerol phosphate residue at its C3 atom. The teichoic acid structure was established by chemical analysis and 13C-NMR spectroscopy. There also is a peptidoglycan belonging to the A1 gamma type: as well as meso-2,6-diaminopimelic acid it contains small amounts of the LL form and glycine.
