OGG1 acts as an N-glycosylase and a DNA beta-lyase to excise 8-oxoguanine (8oxoG) from dsDNA, creating an apurinic/apyrimidinic (AP) site, and to nick the DNA sugar-phosphate backbone 5' to the AP site, creating a single strand break (SSB) (Aburatani et al. 1997, Rosenquist et al. 1997, Roldan-Arjona et al. 1997, Radicella et al. 1997, Bjoras et al. 1997, Bruner et al. 2000).
