Аннотация:
The cell walls of two strains of the genus Promicromonospora (phylum Actinobacteria) were found to
include non-phosphorylated anionic glycopolymers with pyruvic acid acetals of R-configuration. The cell
wall of the type strain P. citrea 665T contains two glycopolymers of the sort, including the Kdnteichulosonic acid with the repeating unit /6)-a-D-Glсp//6)-a-D-Glсp3SO3-(1 / 4)-a-[7,9Pyr]-Kdn-(2/, and the galactan with the repeating unit /3)-a-[4,6Pyr]-D-Galp-2OAc-(1 / . The cell wall of
Promicromonospora sp.VKM Ac-1028 contains the teichuronic acid with the repeating unit /6)-a-DGlсp-(1
/ 4)-b-[2,3Pyr]-D-GlcpA-(1 / . The detected glycopolymer structures are reported for the first
time. Presented results expand the notion on the diversity of the organic world and on the role of the
structures and composition of cell wall polymers in bacterial taxonomy. The glycopolymer structures
were established by using a combination of chemical methods, NMR- and IR-spectroscopy, and ESI MS.
