HPLC chromatograms of crude extract from S. fradiae ΔurdQ/R and from S. fradiae ΔurdQ/R expressing different genes. First lane: detection of urdamycin X (1) in S. fradiae ΔurdQ/R; second lane: detection of urdamycin I (2) and urdamycin J (3) in S. fradiae ΔurdQ/R expressing oleL and oleU; third lane: detection of aquayamycin (4) and urdamycinone B (5) in S. fradiae ΔurdQ/R expressing urdR; fourth lane: detection of urdamycin A (6) and urdamycin B (7) in S. fradiae ΔurdQ/R expressing lanR and lanQ; fifth lane: detection of urdamycin M (8) in S. fradiae ΔurdQ/R expressing urdQ. Compounds were identified by UV- and MS-spectroscopy (structures of compounds are shown in Figs. 1 and 2).
