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].

Eythylbenzene dehydrogenase is a heterotrimer of three subunits that catalyses the anaerobic degradation of hydrocarbons. The alpha subunit contains the catalytic centre as a Molybdenum cofactor-complex. This removes an electron-pair from the hydrocarbon and passes it along an electron transport system involving iron-sulphur complexes held in the beta subunit and a Haem b molecule contained in the gamma subunit. The electron-pair is then subsequently passed to an as yet unknown receiver [1]. The enzyme is found in a variety of different bacteria.	Domain
