CC   -!- FUNCTION: Member of gene cluster sufABCDSE that mediates iron-sulfur
CC       cluster assembly under oxidative stress and iron limitation conditions
CC       (PubMed:17941825). Binds [2Fe2S] cluster by mobilizing sulfur atoms
CC       provided by the SufS-SufE cysteine desulfurase system and then
CC       transfers the assembled Fe-S cluster to target proteins including
CC       ferredoxin and aconitase (PubMed:17350000, PubMed:19366265). Seems to
CC       act as a Fe-S cluster carrier rather than a scaffold, this role being
CC       performed by SufB and SufC (PubMed:19810706, PubMed:23018275).
CC       {ECO:0000269|PubMed:17350000, ECO:0000269|PubMed:17941825,
CC       ECO:0000269|PubMed:19366265, ECO:0000269|PubMed:19810706,
CC       ECO:0000269|PubMed:23018275}.
CC   -!- SUBUNIT: Homodimer (PubMed:16298366). Interacts with SufB and SufC
CC       (PubMed:19810706). {ECO:0000269|PubMed:16298366,
CC       ECO:0000269|PubMed:19810706}.
CC   -!- INTERACTION:
CC       P77667; P77522: sufB; NbExp=5; IntAct=EBI-1125011, EBI-562758;
CC       P77667; P77499: sufC; NbExp=5; IntAct=EBI-1125011, EBI-561601;
CC   -!- DISRUPTION PHENOTYPE: Deletion has only a mild effect on cell growth
CC       (PubMed:17941825). However, deletion of both IscA and SufA results in a
CC       severe growth phenotype in minimal medium under aerobic growth
CC       conditions (PubMed:17941825). {ECO:0000269|PubMed:17941825}.
CC   -!- SIMILARITY: Belongs to the HesB/IscA family. {ECO:0000305}.
