Molecular function

3 Fe 4 S cluster binding, 3 iron, 4 sulphur cluster binding, 3Fe-4S cluster binding, iron-sulfur cluster 3Fe-4S binding, iron-sulphur cluster 3Fe-4S binding, triiron tetrasulfide cluster binding, triiron tetrasulphide cluster binding

Binding to a 3 iron, 4 sulfur (3Fe-4S) cluster; this cluster consists of three iron atoms, with the inorganic sulfur atoms found between the irons and acting as bridging ligands. It is essentially a 4Fe-4S cluster with one iron missing.
