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].
