title: Direct electrochemical probes of redox protein and redox enzyme structure and function.
abstract: The direct electrochemistry of redox proteins has been achieved at a variety of electrodes, including modified gold and pyrolytic graphite. Careful design of electrode surfaces and electrolyte conditions are required for the attainment of rapid and reversible protein-electrode interaction. Protein-protein complexes can be studied by using selective electrode surfaces. The "well-behaved" electrochemistry of redox proteins can be exploited by coupling the electrode reaction to enzymes for which the redox proteins act as cofactors. The electron-transfer reactions of more complex systems, such as redox enzymes, are now being examined.
