CC   -!- FUNCTION: Subunits I and II form the functional core of the enzyme
CC       complex. Electrons originating in cytochrome c are transferred via heme
CC       a and Cu(A) to the binuclear center formed by heme a3 and Cu(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         ChEBI:CHEBI:29034; EC=7.1.1.9;
CC   -!- COFACTOR:
CC       Name=Cu cation; Xref=ChEBI:CHEBI:23378; Evidence={ECO:0000250};
CC       Note=Binds a copper A center. {ECO:0000250};
CC   -!- COFACTOR:
CC       Name=heme; Xref=ChEBI:CHEBI:30413; Evidence={ECO:0000250};
CC   -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000305}; Multi-pass membrane
CC       protein {ECO:0000305}.
CC   -!- SIMILARITY: Belongs to the cytochrome c oxidase subunit 2 family.
CC       {ECO:0000305}.
