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:0000305|PubMed:30598554}.
CC -!- PATHWAY: Energy metabolism; oxidative phosphorylation.
CC -!- SUBUNIT: Component of the cytochrome c oxidase (complex IV, CIV), a
CC multisubunit enzyme composed of 12 subunits. The complex is composed of
CC a catalytic core of 3 subunits COX1, COX2 and COX3, encoded in the
CC mitochondrial DNA, and 9 supernumerary subunits COX4, COX5A (or COX5B),
CC COX6, COX7, COX8, COX9, COX12, COX13 and COX26, which are encoded in
CC the nuclear genome (PubMed:7851399, PubMed:30598556, PubMed:30598554).
CC The complex exists as a monomer or a dimer and forms supercomplexes
CC (SCs) in the inner mitochondrial membrane with a dimer of ubiquinol-
CC cytochrome c oxidoreductase (cytochrome b-c1 complex, complex III,
CC CIII), resulting in 2 different assemblies (supercomplexes III(2)IV and
CC III(2)IV(2)) (PubMed:10775262, PubMed:10764779, PubMed:30598556,
CC PubMed:30598554). {ECO:0000269|PubMed:10764779,
CC ECO:0000269|PubMed:10775262, ECO:0000269|PubMed:30598554,
CC ECO:0000269|PubMed:30598556, ECO:0000269|PubMed:7851399}.
CC -!- SUBCELLULAR LOCATION: Mitochondrion inner membrane
CC {ECO:0000269|PubMed:30598554}; Peripheral membrane protein
CC {ECO:0000269|PubMed:30598554}; Matrix side
CC {ECO:0000269|PubMed:30598554}.
CC -!- MISCELLANEOUS: Present with 9410 molecules/cell in log phase SD medium.
CC -!- SIMILARITY: Belongs to the cytochrome c oxidase subunit 5B family.
CC {ECO:0000305}.
