CC   -!- FUNCTION: Component of the cytochrome c oxidase, the last enzyme in the
CC       mitochondrial electron transport chain which drives oxidative
CC       phosphorylation. The respiratory chain contains 3 multisubunit
CC       complexes succinate dehydrogenase (complex II, CII), ubiquinol-
CC       cytochrome c oxidoreductase (cytochrome b-c1 complex, complex III,
CC       CIII) and cytochrome c oxidase (complex IV, CIV), that cooperate to
CC       transfer electrons derived from NADH and succinate to molecular oxygen,
CC       creating an electrochemical gradient over the inner membrane that
CC       drives transmembrane transport and the ATP synthase. Cytochrome c
CC       oxidase is the component of the respiratory chain that catalyzes the
CC       reduction of oxygen to water. Electrons originating from reduced
CC       cytochrome c in the intermembrane space (IMS) are transferred via the
CC       dinuclear copper A center (CU(A)) of Cox2 and heme A of Cox1 to the
CC       active site in Cox1, a binuclear center (BNC) formed by heme A3 and
CC       copper B (CU(B)). The BNC reduces molecular oxygen to 2 water molecules
CC       using 4 electrons from cytochrome c in the IMS and 4 protons from the
CC       mitochondrial matrix. {ECO:0000250|UniProtKB:P10174}.
CC   -!- PATHWAY: Energy metabolism; oxidative phosphorylation.
CC       {ECO:0000250|UniProtKB:P10174}.
CC   -!- SUBUNIT: Component of the cytochrome c oxidase (complex IV, CIV), a
CC       multisubunit enzyme composed of 11 subunits. The complex is composed of
CC       a catalytic core of 3 subunits Cox1, Cox2 and Cox3, encoded in the
CC       mitochondrial DNA, and 8 supernumerary subunits Cox4, Cox5a/Cox5, Cox6,
CC       Cox7, Cox8, Cox7a/Cox9, Cox6b/Cox12 and Cox6a/Cox13, which are encoded
CC       in the nuclear genome (PubMed:31316820). The complex exists as a
CC       monomer or a dimer and forms respiratory supercomplexes (SCs) in the
CC       inner mitochondrial membrane with NADH-ubiquinone oxidoreductase
CC       (complex I, CI) and ubiquinol-cytochrome c oxidoreductase (cytochrome
CC       b-c1 complex, complex III, CIII), resulting in various different
CC       assemblies (supercomplexes I(1)IV(1), I(1)III(3)IV(2), III(2)IV(1) and
CC       III(2)IV(2) as well as larger supercomplexes of compositions like
CC       I(1)III(2)IV(5-6)) (PubMed:17873079). {ECO:0000269|PubMed:17873079,
CC       ECO:0000269|PubMed:31316820}.
CC   -!- SUBCELLULAR LOCATION: Mitochondrion inner membrane
CC       {ECO:0000269|PubMed:31316820}; Single-pass membrane protein
CC       {ECO:0000269|PubMed:31316820}.
CC   -!- SIMILARITY: Belongs to the cytochrome c oxidase VIIa family.
CC       {ECO:0000305}.
