ABSTRACT
A glycopolymer of novel structure was found in the cell wall of plant pathogen Clavibacter phaseoli VKM Ac-2641T (family Microbacteriaceae, class Actinomycetes). The glycopolymer was (1 â 6)-linked ß-d-galactofuranan with side branched trisaccharide, α-D-Manp-(1 â 2)-[α-D-Manp-(1 â 3)]-α-D-Ribf-(1â at O-2 on every second galactofuranose residue. The galactofuranan structure was established by chemical and NMR spectroscopic methods using one- and two-dimensional techniques 1H,1H COSY, TOCSY, ROESY and 1H,13C HSQC, HMBC. The results of this study provide new data on diversity of bacterial glycopolymers, may prove useful for bacterial taxonomy and contribute to the understanding of the host plant-microbiota interaction mechanisms.
