H2O2 production by human FMO2.1, the N413K and S195L FMO2 allelic variants and FMO3. Enzymes were incubated for 30 minutes at pH 7.4, 37°C, in the absence (open bars) or presence (solid gray bars) of 75 μM ethionamide. Catalase was added to enzymes in the absence (hatched bars) or presence (solid black bars) of ethionamide. The yield of H2O2 was determined by the Amplex Red assay. Note: hFMO3 was measured only in the presence of substrate ± catalase.
