Interaction
Subunit
Component of the cytochrome c oxidase (complex IV, CIV), a multisubunit enzyme composed of a catalytic core of 3 subunits and several supernumerary subunits. The complex exists as a monomer or a dimer and forms supercomplexes (SCs) in the inner mitochondrial membrane with ubiquinol-cytochrome c oxidoreductase (cytochrome b-c1 complex, complex III, CIII).
