  • Title: Evidence for a ferryl Fea3 in oxygenated cytochrome c oxidase.
    Author: Witt SN, Chan SI.
    Journal: J Biol Chem; 1987 Feb 05; 262(4):1446-8. PubMed ID: 3027092.
    Abstract:
    Evidence is reported which shows that a reactive ferryl Fea3/cupric CuB binuclear couple is present at the dioxygen reduction site in "oxygenated" cytochrome c oxidase; when the fully reduced enzyme is reoxidized at low temperatures; and when partially reduced cytochrome c oxidase is reoxidized with dioxygen at room temperature.
