Abstract

A polymeric fraction (the O-antigenic side-chain) has been isolated from the lipopolysaccharide of Burkholderia gladioli pv. gladioli strain NCPPB 1891 after mild acid hydrolysis. The components of the polymer and their molar proportions were l-Rha (1), d-Gal (1), d-Man (1), and O-acetyl (1). By means of chemical degradations and NMR studies, the repeating unit of the polymer was shown to be a linear trisaccharide of the structure shown.

A structure of the repeating unity of the O antigen of Burkholderia gladioli pv. gladioli has been proposed.

      The signal of δ 5.31 ppm might be α-linked (1→2) Mannose [51]. The 13C NMR spectrum in Fig. 7b showed that the signals at δ100.5–102.9 ppm were assigned to C-1 of Mannose [52]. Characteristic signals of the ring carbons were appeared in the region between δ 65.4 and 78.7 ppm.

      B20. We believe it is especially important to reinvestigate the exact configuration of the sugar residues in these naturally occurring phenolic glycosides as different strains of B. gladioli (ICMP11096 and NCPPB 1891) [42–44] were shown to produce polysaccharides incorporating rhamnose residues in both l- and d-configurations and in either α- or β-glycosidic linkages. That being said, the anomeric linkage of the xylose residue is confirmed to be 1,2-trans with 3JH1,H2 values of 7.8 and 7.6 Hz for natural gladiosides I and II, respectively.

      This conclusion was also supported by assignment of the 1H and 13C NMR spectra for AP-2 (Fig. 2). From a comparison of the 13C NMR spectral data reported for mannan and manno-oligosaccharides [19–21], all the anomeric and other signals in the 13C NMR spectra were assigned as shown in Table 3. Complete signal assignment of the 1H NMR spectrum (Table 3) was also carried out in combination with the spectral data of the COSY, HOHAHA (Fig. 3) and HMQC (Fig. 4) techniques.
