Protein

Cytochrome c oxidase subunit 2

Gene

COII

Organism
Exeristes roborator (Parasitoid wasp)
Status
Reviewed-Annotation score: -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

Cu cationNote: Binds a copper A center.
