IPR013833

Source: InterPro

Description

IPR013833 is a Cytochrome c oxidase, subunit III, 4-helical bundle.

<p>Cytochrome c oxidase ([ec:7.1.1.9]) is the terminal enzyme of the respiratory chain of mitochondria and many aerobic bacteria. It catalyzes the transfer of electrons from reduced cytochrome c to molecular oxygen:</p> <p><reaction>4 cytochrome c<sup>+2</sup>+ 4 H<sup>+</sup>+ O<sub>2</sub>-->4 cytochrome c<sup>+3</sup>+ 2 H<sub>2</sub>O</reaction></p> <p>This reaction is coupled to the pumping of four additional protons across the mitochondrial or bacterial membrane [[cite:PUB00006599], [cite:PUB00033207]].</p>
