A wide conservation of iscSUA genes in nature and evidence that NifU and NifS participate in the mobilization of iron and sulfur for nitrogenase - specific iron - sulfur cluster formation suggest that the products of the iscSUA genes could play a general role in the formation or repair of iron - sulfur clusters .
