Figure 2

Structural characterisation of the O-polysaccharide (OPS) chain moiety from LPSB.a. (A) Zoom of the overlapped 1H and 1H, 13C HSQC spectra of the OPS from LPSB.a. after mild acid treatment. The heteronuclear correlations are indicated. Numbering of sugar residues is as reported in Table S1. (B) Zoom of the overlapped 1H, 1H, 13C HMBC spectra. The key inter-residual long-range correlations involving sugar moieties (A–C, Table S2) are indicated in red, whereas the intra-residual long-range contacts are reported in black; letters are as in Table S1. The one-bond heteronuclear correlation involving the C-methyl group of residue A is also reported in the spectrum. (C) The structure of the elucidated trisaccharide repeating unit of the LPSB.a. OPS moiety.
