Direct electrochemistry of redox proteins at pyrolytic graphite electrodes

Journal of the American Chemical Society, 1984
The direct (unmediated) electrochemistry of several redox proteins at pyrolytic graphite electrodes has been studied by square-wave voltammetry. For rubredoxin and the 2 left bracket 4Fe-4S right bracket ferrodoxin from Clostridium pasteurianum and flavodoxin from Megasphaera elsdenii rapid heterogeneous electron transfer is promoted by multivalent ...
