Effects of bc1-site electron transfer inhibitors on the absorption spectra of mitochondrial cytochromes b.
Changes are described that are brought about by antimycin, NoHOQnO, funiculosin, myxothiazol and mucidin in the alpha-, beta- and gamma-absorption bands of reduced and oxidized cytochromes b in the isolated complex bc1 form beef heart mitochondria. The inhibitors can be divided into 2 groups. Antimycin, funiculosin and NoHOQnO are likely to shift the spectrum of b-562 and compete for specific binding with complex bc1, with each other but not with myxothiazol and mucidin. The spectral effects of the latter two inhibitors are more difficult to interpret and may involve contributions not only from b-562 but from b-566 as well. The existence of 2 independent inhibitor binding-sites in the complex bc1 corroborates the Q-cycle hypothesis.

Effect of electron transfer inhibitors on superoxide generation in the cytochrome bc1 site of the mitochondrial respiratory chain.
Antimycin, 2-nonyl-4-hydroxyquinoline N-oxide and funiculosin induce O.2(-) generation by submitochondrial particles oxidizing succinate, whereas KCN, mucidin, myxothiazol or 2,3-dimercaptopropanol inhibit O.2(-) generation. Thenoyltrifluoroacetone does not induce superoxide production by itself but slightly stimulates the reaction initiated by antimycin. The results indicate that auto-oxidation of unstable ubisemiquinone formed in centre o of the Q-cycle generates most of the O.2(-) radicals in the cytochrome bc1-site of the mitochondrial respiratory chain.
