WebMar 21, 2024 · Cytochrome c oxidase (COX) is the terminal enzyme of the mitochondrial respiratory chain. It is a multi-subunit enzyme complex that couples the transfer of electrons from cytochrome c to molecular oxygen and contributes to a proton electrochemical gradient across the inner mitochondrial membrane. WebFeb 14, 2024 · Abstract Cytochrome c oxidase (COX) is regulated through tissue-, development- or environment-controlled expression of subunit isoforms. The COX4 subunit is thought to optimize respiratory chain function according to oxygen-controlled expression of its isoforms COX4i1 and COX4i2.
WebThe mitochondrial cytochrome c oxidases possess a core consisting of three protein subunits. These subunits are encoded by the mitochondrial genome. Subunit I is the largest subunit and possesses between 500 and 600 amino acid residues. It binds heme a as well as the heme a3 –Cu B binuclear center and is the major catalytic subunit.
