The key element of this domain is the CX31-38CCX33-34CXXC sequence motif normally found at the C-terminus in archaeal and bacterial Hdr-like proteins [2]. There may be one or two copies, and the motif is probably an iron-sulfur binding cluster. In some instances one of the cysteines is replaced by an aspartate, and aspartate can in principle also function as a ligand of an iron-sulfur cluster [2]. The entry includes a subunit from heterodisulphide reductase and a subunit from glycolate oxidase (Swiss:P52074) [1] and glycerol-3-phosphate dehydrogenase.	Domain

Coenzyme F420 hydrogenase (EC:1.12.99.1) reduces the low-potential two-electron acceptor coenzyme F420. 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 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].
