Identifier	ISCA
Protein name	RecName: Full=Iron-binding protein IscA; AltName: Full=Iron-sulfur cluster assembly protein;
Gene name	Name=iscA;

Comments [?]

FUNCTION	Is able to transfer iron-sulfur clusters to apo-ferredoxin. Multiple cycles of [2Fe2S] cluster formation and transfer are observed, suggesting that IscA acts catalytically. Recruits intracellular free iron so as to provide iron for the assembly of transient iron-sulfur cluster in IscU in the presence of IscS, L-cysteine and the thioredoxin reductase system TrxA/TrxB.
case <FTGroup:1>
COFACTOR	Name=Fe cation; Xref=ChEBI:CHEBI:24875; Note=Binds 2 iron ions per dimer. The dimer may bind additional iron ions.;
end case
SUBUNIT	Homodimer; may form tetramers and higher multimers.
SIMILARITY	Belongs to the HesB/IscA family.
