Direct regulation of cytochrome c oxidase by calcium ions.

Direct regulation of cytochrome c oxidase by calcium ions.

Cytochrome c oxidase from bovine heart binds Ca(2+) reversibly at a specific Cation Binding Site located near the outer face of the mitochondrial membrane. Ca(2+) shifts the absorption spectrum of heme a, which allowed previously to determine the kinetics and equilibrium characteristics of the bindi...
