IntEnz Enzyme Nomenclature


Accepted name:
carbon-monoxide dehydrogenase (acceptor)
Other names:
anaerobic carbon monoxide dehydrogenase
carbon monoxide oxygenase
carbon-monoxide dehydrogenase
carbon-monoxide:(acceptor) oxidoreductase
Systematic name:
carbon-monoxide:acceptor oxidoreductase




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, hydrogenase (acceptor), which catalyses the overall reaction: CO + H2O = CO2 + H2.
