Аннотация:The major cell wall polymer of Kineosporia aurantiaca VKM Ac-702(T) a representative of the suborder Frankineae, is a galactomannan with a repeating unit of the following structure: -> 3)-beta-D-Galp-(1 -> 6)-beta-D-Manp-(1 -> 4)-beta-D-Manp-(1 -> 3)-beta-D-Galp-(1 -> 4)-beta-D-Manp-(1 -> 4)-beta-D-Manp-(1 -> that has not been reported so far. This was established using chemical degradation methods and NMR spectroscopy. The polysaccharide identified in the present study provides the second example of neutral galactomannans in actinomycete cell walls. The cell wall of K aurantiaca VKM Ac-702(T) also contains a minor teichoic acid, viz., 1,3-poly(glycerol phosphate) partially substituted with a-glucosamine residues, only part of which are N-acetylated.
