Protein

Cytochrome c oxidase subunit 2

Gene
mt:CoII, CoII
Organism
Drosophila narragansett (Fruit fly)
Status
Reviewed - Annotation score: 3 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. Subunit 2 transfers the electrons from cytochrome c via its binuclear copper A center to the bimetallic center of the catalytic subunit 1.

Catalytic activityi

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

Cofactori

Copper A.
