Аннотация: Abstract—The cell wall of Actinoplanes utahensis VKM Ac674T contains two anionic polymers: teichoic acid 1,3poly(glycerol phosphate) that is widespread in cell walls of Grampositive bacteria; and a unique teichulosonic acid belonging to a new class of bioglycans described only in microorganisms of the Actinomycetales order. The latter polymer contains residues of di-N-acyl derivative of sialic acid-like monosaccharide – 5,7-diamino-3,5,7,9-tetradeoxy-L-glycero-β-L-mannonon-2-ulosonic or pseudaminic acid (Pse) which bears the N(3,4dihydroxybutanoyl) group (Dhb) at C7. This polymer has irregular structure and consists of fragments of two types, which differ in substitution of the Dhb residues at O4 either with β-D-glucopyranose or with β-Pse residues. Most of the βPse residues (~80%) are glycosylated at position 4 with α-D-galac topyranose residues in both types of fragments. The glucose, galactose, and Dhb residues are partly O-acetylated. The structures of the polymers were established by chemical and NMR spectroscopy methods.
