Iron-binding protein IscA

Gene

iscA

Organism
Cronobacter sakazakii (strain ATCC BAA-894) (Enterobacter sakazakii)
Status
Reviewed-Annotation score: -Protein inferred from homologyi

Functioni

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.UniRule annotation
