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.

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.

Developmental stage

Free in soil (not as bacteroid).

Sequence similarities

Belongs to the heme-copper respiratory oxidase family.
