Аннотация: 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 → 6)-linked β-D-galactofuranan withside branched trisaccharide, α-D-Manp-(1 → 2)-[α-D-Manp-(1 → 3)]-α-D-Ribf-(1→ at O-2 on every second galactofuranoseresidue. The galactofuranan structure was established by chemical and NMR spectroscopic methodsusing one- and two-dimensional techniques 1H,1H COSY, TOCSY, ROESY and 1H,13C HSQC, HMBC. The results ofthis study provide new data on diversity of bacterial glycopolymers, may prove useful for bacterial taxonomy andcontribute to the understanding of the host plant-microbiota interaction mechanisms.
