Diheme Cytochrome c: Structure–Function Correlation and Effect of Heme−Heme Interactions

We explore here the structure–function relationship of the diheme cytochrome c using synthetic diheme analogs which serve as a convenient tool to investigate various aspects of Nature’s sophisticated design in vitro. A large series of diiron ethane-bridged porphyrin dimers, both in the oxidized and the reduced states, are synthesized and their structural, chemical, and electrochemical properties have been scrutinized. Interestingly, the...
