The subject of the present review is the structural diversity and abundance of cell wall teichuronic and teichulosonic acids of representatives of the order Actinomycetales. Recently found teichulosonic acids are a new class of natural glycopolymers with ald-2-ulosonic acid residues: Kdn (3-deoxy-D-glycero-D-galacto-non-2-ulosonic acid) or di-N-acyl derivatives of Pse (5,7-diamino-3,5,7,9-tetradeoxy-L-glycero-L-manno-non-2-ulosonic or pseudaminic acid) as the obligatory component. The structures of teichuronic and teichulosonic acids are presented. Data are summarized on the occurrence of the glycopolymers of different nature in the cell wall of the studied actinomycetes. The biological role of the glycopolymers and their possible taxonomic implication are discussed. The comprehensive tables given in the Supplement show (13)C NMR spectroscopic data of teichuronic and teichulosonic acids obtained by the authors.
