A PF00384 Molybdopterin Molybdopterin oxidoreductase Family
A PF04879 Molybdop_Fe4S4 Molybdopterin oxidoreductase Fe4S4 domain Domain This domain is found in formate dehydrogenase H for which the structure is known. The first domain (residues 1 to 60, 448 to 476, and 499 to 540), comprising two small antiparallel sheets and four helices, coordinates the Fe4S4 cluster just below the protein surface [1]. PFAM PF04879
A PF01568 Molydop_binding Molydopterin dinucleotide binding domain Domain 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]. PFAM PF01568
