ENZYME entry: EC 1.2.5.3

Accepted Name
aerobic carbon monoxide dehydrogenase.
Alternative Name(s)
molybdoenzyme carbon monoxide dehydrogenase.
Reaction catalysed
a quinone + CO + H2O <=> a quinol + CO2
Comment(s)
  • This enzyme, found in carboxydotrophic bacteria, catalyzes the oxidation of CO to CO2 under aerobic conditions.
  • The enzyme 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.
  • Cf. EC 1.2.7.4.
