Superfamily	Cytochrome c oxidase, subunit III, four-helix bundle
Functional Family	Cytochrome c oxidase subunit 3

Enzyme Information

1.9.3.1

Cytochrome-c oxidase.

based on mapping to UniProt P00420

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.
