Аннотация:A hexasaccharide 1phosphate polymer of original structure and two teichoic acids (TA) belonging to different structural types were found in Arthrobacter uratoxydans VKM Ac1979T
cell wall. The poly(hexasaccharide 1phosphate)combines features of teichuronic acids and glycosyl 1phosphate polymers, and its structure has never been reported earlier. Its composition includes residues of α and βDglucuronic acid as well as αDgalacto, βDgluco, αDmannopy ranose, and 6Oacetylated 2acetamido2deoxyαDglucopyranose. The phosphodiester bond in the polymer joins the glycoside hydroxyl of αDglucuronic acid and O6 of
α-D-Galactopyranose. TA 1 is βDglycosylated 1,3poly(glycerol phosphate), and TA 2 is 3,6linked poly[αDglucosyl(1→2)polyol phosphate]. The phosphatecontaining polymers were studied by chemical methods and on the basis of onedimensional 1H, 13C, and 31PNMR spectra, omonuclear two dimensional 1H/1H COSY, TOCSY, ROESY, and heteronuclear 1H/13C HSQC, HSQCTOCSY, HMBC, and 1H/31P HMBC experiments. The set and structure of the polymers revealed as well as the cell wall sugars (galactose, glucose, mannose, glucosamine) and glycerol can be used in microbiological practice for taxonomic purposes.
