General annotation (Comments)

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 By similarity.
Catalytic activity	4 ferrocytochrome c + O₂ + 4 H⁺ = 4 ferricytochrome c + 2 H₂O.
Pathway	Energy metabolism; oxidative phosphorylation.
Subcellular location	Cell membrane; Multi-pass membrane protein.
Sequence similarities	Belongs to the heme-copper respiratory oxidase family.
