Abstract
- The suf operon encoding a Fe-S assembly system is induced by peroxides through activators OxyR and IscR in Escherichia coli. For apo-IscR to bind, oxidation-mediated dissociation of Fur is required. Therefore, a peroxide-responsive signal is transduced through OxyR, IscR, and Fur to achieve oxidation-sensitive and maximal induction of this operon.
