General annotation (Comments)
| Function | Cytochrome c oxidase is the component of the respiratory chain that catalyzes the reduction of oxygen to water. Subunits 1-3 form the functional core of the enzyme complex. CO I is the catalytic subunit of the enzyme. Electrons originating in cytochrome c are transferred via the copper A center of subunit 2 and heme A of subunit 1 to the bimetallic center formed by heme A3 and copper B. |
| Catalytic activity | 4 ferrocytochrome c + O2 + 4 H+ = 4 ferricytochrome c + 2 H2O. |
| Pathway | |
| Subcellular location | |
| Sequence similarities | Belongs to the heme-copper respiratory oxidase family. |
