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).
CC {ECO:0000256|ARBA:ARBA00024688, ECO:0000256|RuleBase:RU004024}.
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 cation; Xref=ChEBI:CHEBI:23378;
CC Evidence={ECO:0000256|RuleBase:RU004024};
CC Note=Binds a copper A center. {ECO:0000256|RuleBase:RU004024};
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000256|RuleBase:RU000456};
CC Multi-pass membrane protein {ECO:0000256|RuleBase:RU000456}. Membrane
CC {ECO:0000256|ARBA:ARBA00004141}; Multi-pass membrane protein
CC {ECO:0000256|ARBA:ARBA00004141}.
CC -!- SIMILARITY: Belongs to the cytochrome c oxidase subunit 2 family.
