| Description | The [2Fe-2S] binding domain is found in a range of enzymes including dehydrogenases, oxidases and oxidoreductases.The aldehyde oxido-reductase (Mop) from the sulphate reducing anaerobic Gram-negative bacterium Desulfovibrio gigas is a homodimer of 907 amino acid residues subunits and is a member of the xanthine oxidase family. The protein contains a molybdopterin cofactor (Mo-co) and two different [2Fe-2S] centres. It is folded into four domains of which the first two bind the iron sulphur centres and the last two are involved in Mo-co binding. Mo-co is a molybdenum molybdopterin cytosine dinucleotide. Molybdopterin forms a tricyclic system with the pterin bicycle annealed to a pyran ring. The molybdopterin dinucleotide is deeply buried in the protein. The cis-dithiolene group of the pyran ring binds the molybdenum, which is coordinated by three more (oxygen) ligands []. | Name | [2Fe-2S]-binding domain superfamily |
