Enzyme mechanism-based, oxidative DNA–protein cross-links formed with DNA polymerase β in vivo
Free radical attack on the C1′ position of DNA deoxyribose generates the oxidized abasic (AP) site 2-deoxyribonolactone (dL). Upon encountering dL, AP lyase enzymes such as DNA polymerase β (Polβ) form dead-end, covalent intermediates in vitro during attempted DNA repair. However, the conditions tha...
