In enzymology, a carbon-monoxide dehydrogenase (ferredoxin) () is an enzyme that catalyzes the chemical reaction CO + H2O + oxidized ferredoxin CO2 + reduced ferredoxin 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. References EC 1.2.7 Enzymes of unknown structure Carbon monoxide
