Structure of anionic carbohydrate-containing cell wall polymers in several representatives of the order actinomycetales

Biochemistry (Mosc). 2000 Oct;65(10):1212-8.

Abstract

A new teichoic acid was identified in the cell walls of Streptomyces griseoviridis VKM Ac-622T, Streptomyces sp. VKM Ac-2091, and Actinoplanes campanulata VKM Ac-1319T. The polymer is poly(glycosylglycerol phosphate). The repeating units of the polymer, alpha-galactopyranosyl-(1-->3)-2-acetamido-2-deoxy-beta-galactopyran+ ++ osyl-(1-->1)-glycerols, are in phosphodiester linkage at C-3 of glycerol and C-6 of galactose. The structures of cell wall teichoic acids in the strains Streptomyces chryseus VKM Ac-200T and "Streptomyces subflavus" VKM Ac-484 similar in morphology and growth characteristics are also identical: 1,5-poly(ribitol phosphate) substituted at C-4(2) by 2-acetamido-2-deoxy-beta-glucopyranosyl residues and 1,3-poly(glycerol phosphate). The taxonomic aspects of these results are discussed.
