The [4Fe-4S] form diffracted to 1.7 Å and two different types of molecules were found in the crystal. They have different crystal packing and intramolecular disulfide bond conformation. The crystal packing reveals a beta-sheet interaction between A molecules in adjacent asymmetric units, while B molecules are packed as monomers in a less rigid position next to the A-A extended beta-sheet dimers.
