Abstract excerpt
(1) Short flash excitation of membrane vesicles of a cytochrome-c2-deficient mutant of Rhodobacter capsulatus (strain MT-G4/S4) led to rapid oxidation of a c-type cytochrome. In redox titrations, the photooxidation of c-type cytochrome was attenuated with a midpoint of approx. +360 mV. Vesicles from a control strain, MT1131, gave similar results. These findings are consistent with those of Prince et al. (Prince,...
