== Function ==
[https://www.uniprot.org/uniprot/ISCR_ECOLI ISCR_ECOLI] Regulates the transcription of several operons and genes involved in the biogenesis of Fe-S clusters and Fe-S-containing proteins. Transcriptional repressor of the iscRSUA operon, which is involved in the assembly of Fe-S clusters into Fe-S proteins. In its apoform, under conditions of oxidative stress or iron deprivation, it activates the suf operon, which is a second operon involved in the assembly of Fe-S clusters. Represses its own transcription as well as that of toxin rnlA.<ref>PMID:11742080</ref> <ref>PMID:16824106</ref> <ref>PMID:20421606</ref>
