a 1H NMR spectra of native EpsA-O, sonicated EpsA-O, SD1, SD2, and EpsA-O after solvolysis recorded at 70 °C. Anomeric resonances are labelled with letters and sugar abbreviations, as in Tables 1–3. b Ring region of the SD1 HSQC spectrum recorded at 70 °C. Anomeric and methyl regions are reported in the insets. Cross peaks are labeled as in Table 1 (A1 = H1/C1 of residue A).
