- Аннотация: A hexasaccharide 1-phosphate polymer of original structure and two teichoic acids (TA) belonging to different structural types were found in Arthrobacter uratoxydans VKM Ac-1979(T) cell wall. The poly(hexasaccharide 1-phosphate) combines features of teichuronic acids and glycosyl 1-phosphate polymers, and its structure has never been reported earlier. Its composition includes residues of α- and β-D-glucuronic acid as well as α-D-galacto-, β-D-gluco-, α-D-mannopyranose, and 6-O-acetylated 2-acetamido-2-deoxy-α-D-glucopyranose. The phosphodiester bond in the polymer joins the glycoside hydroxyl of α-D-glucuronic acid and O6 of α-D-galactopyranose. TA 1 is β-D-glucosylated 1,3-poly(glycerol phosphate), and TA 2 is 3,6-linked poly[α-D-glucosyl-(1→2)-glycerol phosphate]. The phosphate-containing polymers were studied by chemical methods and on the basis of one-dimensional 1H-, 13C-, and (31)P-NMR spectra, homonuclear two-dimensional (1)H/(1)H COSY, TOCSY, ROESY, and heteronuclear (1)H/(13)C HSQC, HSQC-TOCSY, HMBC, and (1)H/(31)P 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.
