Beef heart cytochrome c oxidase.
During the past two years, the crystal structures of beef heart cytochrome c oxidase with 13 subunits and the bacterial enzyme with four subunits have been reported at atomic resolution, ushering in a new era for cytochrome c oxidase research. Different proton pumping mechanisms have been proposed for the two organisms.
