LC–MS/MS analysis of the hydrolysis product of 3-oxo-C8-HSL by AiiO-AIO6. MS1 analysis of the 14.44 min HPLC fragment of enzymatic hydrolysates showed a mainprecursor (M−H) ion at m/z of 258.1 (upper panel). MS2 spectra of the precursor ion at m/z of 258.1 by tandem mass spectrometry showed a main fragment ion at m/z 118.1 (bottom panel)
