ABSTRACT
The cell wall of Rathayibacter caricis VKM Ac-1799T (family Microbacteriaceae, class Actinobacteria) was found to contain both neutral and acidic glycopolymers. The first one is D-rhamnopyranan with main chain â2)-α-D-Rhap-(1 â 3)-α-D-Rhap-(1â, where a part of 2-substituted residues bears as a side-chain at position 3 α-D-Manp residues or disaccharides α-D-Araf-(1â2)-α-D-Manp-(1 â . The second polymer is a teichuronic acid with a branched repeating units composed of seven monosaccharides â4)-α-[ß-D-Manp-(1 â 3)]-D-Glcp-(1 â 4)-ß-D-GlcpA-(1 â 2)-ß-[4,6Pyr]-D-Manp-(1 â 4)-ß-L-Rhap-(1 â 4)-ß-D-Glcp-(1 â 4)-ß-D-Glcp-(1 â . The structures of the polymers were determined by chemical and NMR spectroscopic methods.
