(A) Screening results for cytochromes bd-I (light-grey), bd-II (dark-grey) and bo3 (white) for short-chain AurD-type compounds. (B) Screening results for selected AurD-type compounds with decreasing residual activity for cytochrome bo3 from left to right. Inhibition assay using test compounds at 250 µM in presence of 200 µM ubiquinone-1 and 5 mM dithiothreitol. Oxygen reduction activity was calculated from oxygen consumption rates at RT. Reference activity (100%) of each oxidase was determined in presence of DMSO to exclude secondary effects of the solvent. Presented data are mean ± S.E.M. (n = 3) ***p < 0.001, **p < 0.01, *p < 0.05, NSp > 0.05.
