After POLB (DNA polymerase beta) fills a single nucleotide gap created by the APEX1 and POLB-mediated excision of the apurinic/apyrimidinic (AP) site in the damaged DNA strand, LIG3 (DNA ligase 3), recruited to POLB-bound AP site by XRCC1, ligates the two DNA strand fragments, thus completing the base excision repair (Kubota et al. 1996).
