This enzyme, found in carboxydotrophic bacteria, catalyses the oxidation of CO to CO2 under aerobic conditions. The enzyme contains a binuclear Mo-Cu cluster in which the copper is ligated to a molybdopterin center via a sulfur bridge. The enzyme also contains two [2Fe-2S] clusters and FAD, and belongs to the xanthine oxidoreductase family. The CO2 that is produced is assimilated by the Calvin-Benson-Basham cycle, while the electrons are transferred to a quinone via the FAD site, and continue through the electron transfer chain to a dioxygen terminal acceptor [5]. cf. EC 1.2.7.4, anaerobic carbon monoxide dehydrogenase. |
