Enzyme Information

1.9.3.1
Cytochrome-c oxidase.
based on mapping to UniProt Q03736
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.
