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.
