Abstract: | Direct electrochemistry of microperoxidase (the heme-undecapeptide from cytochrome c) has been followed at a bare and a gold plated RVC thin-layer electrode, using the spectropotentiostatic method or voltabsorptometry. Both techniques yield 'clean' and undistorted signals; their analysis easily provides quantitative information for the electrochemical parameters of microperoxidase and shows that spectroelectrochemistry is a powerful method to study the redox behavior of metalloproteins or their active site fragments. |
