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 (By
CC similarity). {ECO:0000250}.
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 Rhea:RHEA-COMP:10350, Rhea:RHEA-COMP:14399, ChEBI:CHEBI:15377,
CC ChEBI:CHEBI:15378, ChEBI:CHEBI:15379, ChEBI:CHEBI:29033,
CC ChEBI:CHEBI:29034; EC=7.1.1.9;
CC -!- COFACTOR:
CC Name=Cu(2+); Xref=ChEBI:CHEBI:29036; Evidence={ECO:0000250};
CC Note=Binds 1 copper B ion per subunit. {ECO:0000250};
CC -!- COFACTOR:
CC Name=heme; Xref=ChEBI:CHEBI:30413; Evidence={ECO:0000250};
CC Note=Binds 2 heme groups per subunit. {ECO:0000250};
CC -!- PATHWAY: Energy metabolism; oxidative phosphorylation.
CC -!- SUBUNIT: Associates with subunits II, III and IV to form cytochrome c
CC oxidase. {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000250}; Multi-pass membrane
CC protein {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the heme-copper respiratory oxidase family.
CC {ECO:0000305}.
