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.
