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: Mitochondrion inner membrane; Multi-pass membrane protein.
SIMILARITY: Belongs to the heme-copper respiratory oxidase family.
