Metal ions are represented as spheres, along with the side chains involved in metal coordination (using a distance cutoff of 3 Å). Protein chains are shown as ribbon models. | Metal ions are represented as spheres, along with the side chains involved in metal coordination (using a distance cutoff of 3 Å).

The metals locate mainly in a region of high density of negative charge, the so-called "<scene name='69/696356/Cv/11'>acidic ridge</scene>", which is also the surface of interaction with the Fe-S cluster assembly machinery. No major changes occurs in FXN structures upon interaction with metals, when derivative structures are compared with the previously determined apo form (PDB ID: [[4hs5]]), but subtle changes in crystallographic B-factors occur in two regions of the protein not in direct contact with metals. This changes suggest localized changes in internal motions, with potential impact in interaction with partner proteins (see the static images below). | The metals locate mainly in a region of high density of negative charge, the so-called "<scene name='69/696356/Cv/11'>acidic ridge</scene>", which is also the surface of interaction with the Fe-S cluster assembly machinery.
