ACIDITHIOBACILLUS FERROOXIDANS CYTOCHROME C4 STRUCTURE SUPPORTS A COMPLEX-INDUCED TUNING OF ELECTRON TRANSFER
Overview
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 ...
