Abstract excerpt

The 8-oxo-7,8-dihydrodeoxyguanosine (8oxoG), a major mutagenic DNA lesion, results either from direct oxidation of guanines or misincorporation of 8oxodGTP by DNA polymerases. At present, little is known about the mechanisms preventing the mutagenic action of 8oxodGTP in Saccharomyces cerevisiae. Herein, we report for the first time the identification of an alternative repair pathway for 8oxoG residues initiated...
