The study of electron transfer between the copper protein rusticyanin, (RCy) and the c(4)-cytochrome CYC(41) of the acidophilic bacterium, Acidithiobacillus ferrooxidans has evidenced a remarkable decrease of, RCy's redox potential upon complex formation. The structure of the CYC(41), obtained at 2.2 A resolution highlighted a specific glutamate residue, (E121) involved in zinc binding as potentially playing a central role in, this effect, required for the electron transfer to occur. EPR and, stopped-flow experiments confirmed the strong inhibitory effect of, divalent cations on CYC(41):RCy complex formation. A docking analysis of, the CYC(41) and RCy structure allows us to propose a detailed model for, the complex-induced tuning of electron transfer in agreement with our, experimental ...

The study of electron transfer between the copper protein rusticyanin (RCy) and the c(4)-cytochrome CYC(41) of the acidophilic bacterium Acidithiobacillus ferrooxidans has evidenced a remarkable decrease of RCy's redox potential upon complex formation. The structure of the CYC(41) obtained at 2.2 A resolution highlighted a specific glutamate residue (E121) involved in zinc binding as potentially playing a central role in this effect, required for the electron transfer to occur. EPR and stopped-flow experiments confirmed the strong inhibitory effect of divalent cations on CYC(41):RCy complex formation. A docking analysis of the CYC(41) and RCy structure allows us to propose a detailed model for the complex-induced tuning of electron transfer in agreement with our experimental data, which could be representative of other copper proteins involved in electron transfer.
