Enzyme Information
| 1.2.7.4 | Anaerobic carbon-monoxide dehydrogenase. based on mapping to UniProt P27989 CO + H(2)O + 2 oxidized ferredoxin = CO(2) + 2 reduced ferredoxin + 2 H(+). -!- This prokaryotic enzyme catalyzes the reversible reduction of CO(2) to CO. -!- The electrons are transferred to redox proteins such as ferredoxin. -!- In purple sulfur bacteria and methanogenic archaea it catalyzes the oxidation of CO to CO(2), which is incorporated by the Calvin-Benson- Basham cycle or released, respectively. -!- In acetogenic and sulfate-reducing microbes it catalyzes the reduction of CO(2) to CO, which is incorporated into acetyl CoA by EC 2.3.1.169, with which the enzyme forms a tight complex in those organisms. -!- In purple sulfur bacteria the enzyme forms complexes with the Ni-Fe-S protein EC 1.12.7.2 which catalyze the overall reaction: CO + H(2)O = CO(2) + H(2). -!- Cf. EC 1.2.5.3. -!- Formerly EC 1.2.99.2. |
