E.coli Endonuclease VIII functions as both an N-glycosylase (by excising oxidative base lesions) and an AP lyase (by subsequently cleaving the phosphodiester backbone), leaving terminal phosphates at the 5′ and 3′ ends. (1) Damaged bases removed by Endonuclease VIII include: urea, 5, 6- dihydroxythymine, thymine glycol, 5-hydroxy-5- methylhydanton, uracil glycol, 6-hydroxy-5, 6-dihydrothymine and methyltartronylurea (2,3).
