EC 1.2.99.2     
Accepted name: carbon-monoxide dehydrogenase (acceptor)
Reaction: CO + H2O + A = CO2 + AH2
Other name(s): anaerobic carbon monoxide dehydrogenase; carbon monoxide oxygenase; carbon-monoxide dehydrogenase; carbon-monoxide:(acceptor) oxidoreductase
Systematic name: carbon-monoxide:acceptor oxidoreductase
Comments: Contains a [Ni3Fe-4S] cluster and [4Fe-4S] clusters. It uses many electron acceptors, including ferredoxin, methyl viologen and benzyl viologen and flavins, but not pyridine nucleotides. Forms part of a membrane-bound multienzyme complex with EC 1.12.99.6, hydrogenase (acceptor), which catalyses the overall reaction: CO + H2O = CO2 + H2.
