Fig. 2: Heterologous expression and product characterization of mpa.

Fig. 2:

a, MALDI-TOF mass spectra of the methanol extracts of S. albus J1074 containing mpa (1, m/z 2363; 2, m/z 2232; 3, m/z 2339) and the pBE45 empty vector. Sodium and potassium ions are denoted as ‘+Na’ and ‘+K’. b, Summary of the HR-MS/MS results for compound 1–3. c, key HMBC and COSY correlations for the Dmp moiety in 1. NMR spectra of 1 and assigned signals of Dmp are shown in Supplementary Fig. 14 and Supplementary Table 2, respectively.
