Repair of DNA Lesions Induced by Hydrogen Peroxide in the Presence of Iron Chelators in Escherichia coli: Participation of Endonuclease IV and Fpg

In Escherichia coli, the repair of lethal DNA damage induced by H(2)O(2) requires exonuclease III, the xthA gene product. Here, we report that both endonuclease IV (the nfo gene product) and exonuclease III can mediate the repair of lesions induced by H(2)O(2) under low-iron conditions. Neither the...
