Carbon monoxide dehydrogenase

In enzymology, carbon monoxide dehydrogenase (EC1.2.99.2) is an enzyme that catalyzes the chemical reaction

The 3 substrates of this enzyme are CO, H₂O, and A, whereas its two products are CO₂ and AH₂.

This enzyme belongs to the family of oxidoreductases, specifically those acting on the aldehyde or oxo group of donor with other acceptors. The systematic name of this enzyme class is carbon-monoxide:acceptor oxidoreductase. Other names in common use include anaerobic carbon monoxide dehydrogenase, carbon monoxide oxygenase, carbon-monoxide dehydrogenase, and carbon-monoxide:(acceptor) oxidoreductase.
