WebCytochrome c oxidase, a membrane-bound enzyme in the respiratory chain of aerobic organisms, reduces oxygen to water. This process, which takes place at the binuclear metal center constituted by a heme a3 and a Cu ion, runs via several intermediate states with lifetimes in the micro- and millisecond range. WebCytochrome c oxidases (CcOs) are the terminal enzymes in energy-converting chains of microorganisms, where they reduce oxygen into water. Their affinity for O2 makes them attractive biocatalysts for technological devices in which O2 concentration is limited, but the high overpotentials they display on electrodes severely limit their applicative use. Here, …
