Cytochrome c oxidase subunit 2

Gene

MT-CO2

Organism
Lycalopex griseus (Argentine gray fox) (Pseudalopex griseus)
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.

Cofactori

Cu cationNote: Binds a copper A center.
