| Abstract |
The survival of different DNA repair mutant strains of Escherichia coli treated with H2O2 was evaluated in the presence or absence of an iron chelator (dipyridyl). Our results suggest that Fpg and UvrA proteins participate in vivo in the repair of DNA lesions produced by higher H2O2 concentrations in the presence of an iron chelator while UvrB and UvrC proteins seem to be ineffective in the repair of these lesions. |
