The oxidized and reduced forms of blue copper proteins can coexist in equilibrium in solution. This allows two identical molecules to exchange one electron, giving the so-called electron self-exchange (ESE) reaction (Marcus and Sutin, 1985). The rates of this process usually depend on the pH, temperature, and ionic strength of the solution. When the two forms... 

Marcus theory has been used to interpret the reactions of cytochromes c and blue copper proteins. For thirteen protein-protein electron-transfer reactions, the data can be fitted with the self-exchange rate constants of 2.8 x 10 s ...
