title: The structures of the cell wall teichoic acids from the thermophilic microorganism Geobacillus thermoleovorans strain Fango.
abstract: The structures of two teichoic acid fractions (TA1 and TA2) isolated from the thermophilic gram-positive bacterium Geobacillus thermoleovorans strain Fango were investigated by means of chemical and NMR spectroscopic methods. The most abundant species (TA1) exhibited a rather regular structure comprising two different repeating units of 1,3-glycerol phosphate nonstoichiometrically substituted by terminal-alpha-D-Gal p (t-alpha-D-Gal p). The second molecular species (TA2) presented a higher structural variability and t-alpha-D-Glc p and the disaccharides t-alpha-D-Glc pNAc-(1-->2)-alpha-D-Glc p and t-alpha-D-Glc pNAc-(1-->3)-alpha-D-Glc p were also present as minor substituents at O-2 of the glycerol phosphate residues. Minor substitution by alanine could also be detected.
