P80498 - COX2_SOLTU

Protein

Cytochrome c oxidase subunit 2

Gene

COX2

Organism
Solanum tuberosum (Potato)
Status
Reviewed - Annotation score: 3 out of 5- Experimental evidence at protein leveli
  1. 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
