Molecular function

2 Fe 2 S cluster binding, 2 iron, 2 sulphur cluster binding, 2Fe-2S cluster binding, diiron disulfide cluster binding, diiron disulphide cluster binding, iron-sulfur cluster 2Fe-2S binding, iron-sulphur cluster 2Fe-2S binding

Binding to a 2 iron, 2 sulfur (2Fe-2S) cluster; this cluster consists of two iron atoms, with two inorganic sulfur atoms found between the irons and acting as bridging ligands.
