In enzymology, a formate dehydrogenase (cytochrome) (EC 1.2.2.1) is an enzyme that catalyzes the chemical reaction

 
Fe(III)
Fe(II)
Fe(III)
Fe(II)
 
CO2 + 2 ferrocytochrome b1 + 2 H+
 

This enzyme converts formic acid to carbon dioxide using the cofactor ferricytochrome b1, which is reduced from iron(III) to iron(II).[1][2]

This enzyme belongs to the family of oxidoreductases, specifically those acting on the aldehyde or oxo group of donor with a cytochrome as acceptor. The systematic name of this enzyme class is formate:ferricytochrome-b1 oxidoreductase. Other names in common use include formate dehydrogenase, and formate:cytochrome b1 oxidoreductase. This enzyme participates in glyoxylate and dicarboxylate metabolism.
