Cytochrome c oxidase subunit 1 mitochondrion
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. WebCytochrome c oxidase subunit I (CO1 or MTCO1) is 1 of 3 mitochondrial DNA (mtDNA) encoded subunits (MTCO1, MTCO2, MTCO3) of respiratory Complex IV. Complex IV is located within the mitochondrial inner membrane and is the third and final enzyme of the electron transport chain of mitochondrial oxidative phosphorylation.
