Carbon monoxide dehydrogenase (ferredoxin)

In enzymology, a carbon-monoxide dehydrogenase (ferredoxin) (EC 1.2.7.4) is an enzyme that catalyzes the chemical reaction

The 3 substrates of this enzyme are CO, H₂O, and oxidized ferredoxin, whereas its two products are CO₂ and reduced ferredoxin.

This enzyme belongs to the family of oxidoreductases, specifically those acting on the aldehyde or oxo group of donor with an iron-sulfur protein as acceptor. The systematic name of this enzyme class is carbon-monoxide,water:ferredoxin oxidoreductase.
