    Summary

     

    E.coli homolog from this family, YaaA is a key element of the cellular response to peroxide stress. Induction of YaaA in response to H2O2 reduces intracellular iron levels, thus attenuating the Fenton reaction and the DNA damage that would result from it [PubMed:21378183]. yaaA shows OxyR-dependent induction of expression by hydrogen peroxide [PubMed:11443091][PubMed:21378183]. A yaaA deletion mutant has a growth defect in a catalase/peroxidase-deficient strain background in LB medium. The growth defect can be suppressed by the addition of iron chelators or mutations in iron import [PubMed:21378183].
