Enzyme Information

1.9.3.1

Cytochrome-c oxidase.

based on mapping to UniProt P77921

4 ferrocytochrome c + O(2) + 4 H(+) = 4 ferricytochrome c + 2 H(2)O.

-!- The reduction of O(2) to water is accompanied by the extrusion of four protons from the intramitochondrial compartment. -!- Several bacteria appear to contain analogous oxidases.
