Chains	Enzyme Name	Description	Catalytic Residues
E, F	arsenite oxidase M-CSA #144	Arsenite oxidase oxidises arsenite (As(III)O₃^3-)to the less toxic arsenate (As(V)O₄^3-). The electrons produced are transferred towards the soluble periplasmic electron carriers cytochrome c and/or amicyanin. Arsenite oxidase is a heterodimeric enzyme containing a large and a small subunit. The large catalytic subunit harbours the molybdopterin cofactor (comprising two molybdopterin guanosine dinucleotide cofactors bound to molybdenum), and a [3Fe-4S] cluster; the small subunit belongs to the structural class of the Rieske proteins and contains a Rieske-type [2Fe-2S] clusters.
