The formylmethanofuran dehydrogenase catalyses the first step in methane formation from CO2 in methanogenic archaea and has a molybdopterin dinucleotide cofactor [1]. This domain corresponds to the C-terminal domain IV in dimethyl sulfoxide (DMSO)reductase which interacts with the 2-amino pyrimidone ring of both molybdopterin guanine dinucleotide molecules [2].

This family contains the C termini of F420 hydrogenase and dehydrogenase beta subunits [1], [2]. The N terminus of Methanobacterium formicicum formate dehydrogenase beta chain (EC:1.2.1.2, Swiss:P06130) is also a member of this family [3]. This region is often found in association with the 4Fe-4S binding domain, fer4 (Pfam:PF00037).
