This domain is found in various molybdopterin - containing oxidoreductases and tungsten formylmethanofuran dehydrogenase subunit d (FwdD) and molybdenum formylmethanofuran dehydrogenase subunit (FmdD); where the domain constitutes almost the entire subunit. 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].	Domain
A	PF04879	Molybdopterin oxidoreductase Fe4S4 domain (Molybdop_Fe4S4)	Molybdopterin oxidoreductase Fe4S4 domain	This domain is found in formate dehydrogenase H for which the structure is known. This first domain (residues 1 to 60) of PDB:1aa6 is an Fe4S4 cluster just below the protein surface [1].	Domain
