ID 1.2.7.4 DE anaerobic carbon-monoxide dehydrogenase. AN carbon-monoxide dehydrogenase (ferredoxin). AN Ni-CODH. CA CO + H2O + 2 oxidized [2Fe-2S]-[ferredoxin] = CO2 + 2 H(+) + 2 reduced CA [2Fe-2S]-[ferredoxin]. CC -!- This prokaryotic enzyme catalyzes the reversible reduction of CO2 to CC CO. CC -!- The electrons are transferred to redox proteins such as ferredoxin. CC -!- In purple sulfur bacteria and methanogenic archaea it catalyzes the CC oxidation of CO to CO2, which is incorporated by the Calvin-Benson- CC Basham cycle or released, respectively. CC -!- In acetogenic and sulfate-reducing microbes it catalyzes the CC reduction of CO2 to CO, which is incorporated into acetyl CoA by CC EC 2.3.1.169, with which the enzyme forms a tight complex in those CC organisms. CC -!- In purple sulfur bacteria the enzyme forms complexes with the Ni-Fe-S CC protein EC 1.12.7.2 which catalyze the overall reaction: CO + H2O = CC CO2 + H2. cf. EC 1.2.5.3. CC -!- Formerly EC 1.2.99.2.
