Protein

Cytochrome c oxidase subunit 2

Gene

MT-CO2

Organism
Bos taurus (Bovine)
Status
Reviewed - Annotation score: 4 out of 5- Experimental evidence at protein leveli

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.
