Cytochrome c oxidase subunit I (CO1 or MT-CO1) is one of three mitochondrial DNA (mtDNA) encoded subunits (MT-CO1, MT-CO2, MT-CO3) of respiratory complex IV. Complex IV is the third and final enzyme of the electron transport chain of mitochondrial oxidative phosphorylation. Cytochrome c oxidase (EC 1.9.3.1) is a key enzyme in aerobic metabolism. Proton pumping heme-copper oxidases represent the terminal, energy-transfer enzymes of respiratory chains in prokar… WebJun 24, 2010 · First, the external electron donor—a periplasmic cytochrome c in the case of cbb3 oxidase of P. stutzeri —transfers an electron to the outer heme C molecule of …
