Abstract:Structurally identical teichoic acids were detected in cell walls of two soil isolates assigned to Brevibacterium linens based on phylogenetic data. Both cell walls contain unsubstituted 1,3-poly(glycerol phosphate) and poly(glycosylglycerol phosphate). Repeating units of the latter--alpha-D-GlcpNAc-(1-->4)-beta-D-Galp-(1-->1)-Gro--are bound by phosphodiester bonds including OH-3 of galactose and OH-3 of glycerol. Some of the N-acetylglucosamine residues have 4,6-pyruvic acid acetal, amounts of the latter in the two strains being unequal. Species-specificity of the structures of teichoic acids in the genus Brevibacterium is discussed.
Keywords:Brevibacterium  teichoic acids  poly(glycosylglycerol phosphate)  pyruvic acid acetal
