X-ray structures of catalytic intermediates of cytochrome c oxidase provide insights into its O(2) activation and unidirectional proton-pump mechanisms
Cytochrome c oxidase (CcO) reduces O(2) to water, coupled with a proton-pumping process. The structure of the O(2)-reduction site of CcO contains two reducing equivalents, Fe(a)(3)(2+) and Cu(B)(1+), and suggests that a peroxide-bound state (Fe(a)(3)(3+)–O(−)–O(−)–Cu(B)(2+)) rather than an O(2)-boun...
