CC -!- FUNCTION: Is able to transfer iron-sulfur clusters to apo-ferredoxin.
CC Multiple cycles of [2Fe2S] cluster formation and transfer are observed,
CC suggesting that IscA acts catalytically. Recruits intracellular free
CC iron so as to provide iron for the assembly of transient iron-sulfur
CC cluster in IscU in the presence of IscS, L-cysteine and the thioredoxin
CC reductase system TrxA/TrxB. {ECO:0000255|HAMAP-Rule:MF_01429}.
CC -!- COFACTOR:
CC Name=Fe cation; Xref=ChEBI:CHEBI:24875;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01429};
CC Note=Binds 2 iron ions per dimer. The dimer may bind additional iron
CC ions. {ECO:0000255|HAMAP-Rule:MF_01429};
CC -!- SUBUNIT: Homodimer; may form tetramers and higher multimers.
CC {ECO:0000255|HAMAP-Rule:MF_01429}.
CC -!- SIMILARITY: Belongs to the HesB/IscA family. {ECO:0000255|HAMAP-
CC Rule:MF_01429}.
