Multiple pathways for repair of oxidative DNA damages caused by X rays and hydrogen peroxide in Escherichia coli.

Radiation research - 1 Dec 1992

Abstract excerpt

The responses of Escherichia coli to X rays and hydrogen peroxide were examined in mutants which are deficient in one or more DNA repair genes. Mutant cells deficient in either exonuclease III (xthA) or endonuclease IV (nfo) had normal resistance to X rays, but an xthA-nfo double mutant showed a...
