B PF13247 Fer4_11 4Fe-4S dicluster domain Domain Superfamily includes proteins containing domains which bind to iron-sulfur clusters. Members include bacterial ferredoxins, various dehydrogenases, and various reductases. Structure of the domain is an alpha-antiparallel beta sandwich. Domain contains two 4Fe4S clusters. PFAM PF13247
B PF12800 Fer4_4 4Fe-4S binding domain Domain This superfamily includes proteins containing domains which bind to iron-sulfur clusters. Members include bacterial ferredoxins, various dehydrogenases, and various reductases. Structure of the domain is an alpha-antiparallel beta sandwich. PFAM PF12800
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 PF00384 Molybdopterin Molybdopterin oxidoreductase Family
B PF09163 Form-deh_trans Formate dehydrogenase N, transmembrane Domain Members of this family are predominantly found in the beta subunit of formate dehydrogenase, and consist of a single transmembrane helix. They act as a transmembrane anchor, and allow for conduction of electrons within the protein [1]. PFAM PF09163
C PF00033 Cytochrom_B_N Cytochrome b(N-terminal)/b6/petB Domain PFAM PF00033
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
