Using the NADH-CoQ reductase of Rhodobacter capsulatus as a model for the mitochondrial Complex I, we have for the first time isolated bacterial mutants resistant to piericidin-A, a classical inhibitor of the mitochondrial enzyme. Their sensitivity to other inhibitors directed towards the quinone binding domain of complex I gives direct genetic evidence for the existence of two inhibitor binding sites.
