Abstract
We have electronically wired the cytochrome P450 BM3 heme domain to a graphite electrode with the use of a pyrene-terminated tether. AFM images clearly reveal that pyrene-wired enzyme molecules are adsorbed to the electrode surface. The enzyme-electrode system undergoes rapid and reversible electron transfer, displaying a standard rate constant higher than that of any other P450-electrode system. We also show that the graphite-pyrene-BM3 system catalyzes the four-electron reduction of dioxygen to water.
