Protein

Cytochrome c oxidase subunit 1

Gene
MT-CO1, COI, COXI, MTCO1
Organism
Dasypus novemcinctus (Nine-banded armadillo)
Status
Reviewed - Annotation score: 4 out of 5 - Protein inferred from homologyi

Functioni

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 activityi

4 ferrocytochrome c + O2 + 4 H+ = 4 ferricytochrome c + 2 H2O.
