    ..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. ..

    ..The interaction occurs only if SufC is present. Furthermore, SufB can act as a site for Fe-S cluster assembly in the Suf system. This provides the first evidence of a novel site for Fe-S cluster assembly in the SufBCD complex. ..

    ..While the differences between ISC and SUF were small with respect to the complementing activity, the SUF system appears to be more advantageous for bacterial growth in the presence of hydrogen peroxide. ..
