The nitrate reductase complex is a dimer of heterotrimers each consisting of an alpha, beta and gamma chain. This domain plays a role in the interactions between subunits and shielding of the Fe-S clusters [1]

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].

The nitrate reductase complex is a dimer of heterotrimers each consisting of an alpha, beta and gamma chain. The N-terminal tail of the alpha chain interacts with the beta chain and contributes to the stability of the heterotrimer [1].
