Cytochrome c oxidase subunit 1

Gene

COX1

Organism
Ustilago maydis (strain 521 / FGSC 9021) (Corn smut fungus)
Status
Reviewed-Annotation score: 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.

Pathway: oxidative phosphorylation

This protein is involved in the pathway oxidative phosphorylation, which is part of Energy metabolism.
