EC 1.1.99.33     
Accepted name: formate dehydrogenase (acceptor)
Reaction: formate + acceptor = CO2 + reduced acceptor
Other name(s): FDHH; FDH-H; FDH-O; formate dehydrogenase H; formate dehydrogenase O
Systematic name: formate:acceptor oxidoreductase
Comments: Formate dehydrogenase H is a cytoplasmic enzyme that oxidizes formate without oxygen transfer, transferring electrons to a hydrogenase. The two enzymes form the formate-hydrogen lyase complex [1]. The enzyme contains an [4Fe-4S] cluster, a selenocysteine residue and a molybdopterin cofactor [1].
