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   -!- 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}.
