Function
function
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 activity
- 4 Fe(II)-[cytochrome c] + O2 + 8 H+(in) = 4 Fe(III)-[cytochrome c] + 2 H2O + 4 H+(out)
4 RHEA-COMP:10350 + CHEBI:15379 + 8 H+ (in)CHEBI:15378= 4 RHEA-COMP:14399 + 2 CHEBI:15377 + 4 H+ (out)CHEBI:15378
Pathway
