Flash-induced absorption changes arising from b-type hemes were studied on whole cells of Heliobacillus mobilis under physiological and redox-controlled conditions. The sensitivity of the monitored redox changes to inhibitors of cytochrome bc complexes and the redox potential dependence of reduction and oxidation reactions of cytochrome b-hemes demonstrate that the respective b-hemes are part of a cytochrome bc complex. Both the half-time and the extent of flash-induced reduction of cytochrome… CONTINUE READING
