POLB (DNA polymerase beta) incorporates a single nucleotide to extend the PNKP-processed 3' end of the single strand break (SSB) generated by the beta/delta lyase activity of NEIL1 or NEIL2. POLB thus replaces the excised AP (apurinic/apyrimidinic) deoxyribose phosphate residue (5'dRP) (Wiederhold et al. 2004, Das et al. 2006).
