CC -!- FUNCTION: Cytochrome c oxidase is the component of the respiratory
CC chain that catalyzes the reduction of oxygen to water. Subunits 1-3
CC form the functional core of the enzyme complex. CO I is the catalytic
CC subunit of the enzyme. Electrons originating in cytochrome c are
CC transferred via the copper A center of subunit 2 and heme A of subunit
CC 1 to the bimetallic center formed by heme A3 and copper B.
CC {ECO:0000256|ARBA:ARBA00025218, ECO:0000256|RuleBase:RU363061}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=4 Fe(II)-[cytochrome c] + 8 H(+)(in) + O2 = 4 Fe(III)-
CC [cytochrome c] + 4 H(+)(out) + 2 H2O; Xref=Rhea:RHEA:11436,

CC -!- PATHWAY: Energy metabolism; oxidative phosphorylation.
CC {ECO:0000256|ARBA:ARBA00004673, ECO:0000256|RuleBase:RU363061}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000256|RuleBase:RU363061};
CC Multi-pass membrane protein {ECO:0000256|RuleBase:RU363061}. Membrane
CC {ECO:0000256|ARBA:ARBA00004141}; Multi-pass membrane protein
CC {ECO:0000256|ARBA:ARBA00004141}.
CC -!- SIMILARITY: Belongs to the heme-copper respiratory oxidase family.
