The damaged base is recognized and excised by a DNA glycosylase, resulting often in AP site formation, which is further processed by APE1. Subsequent end-processing generates 3′-OH and 5′-phosphate (5′-P) termini, enabling access of repair Pols. SpletNational Center for Biotechnology Information

SpletThe generated apurinic/apyrimidinic (AP) site can be repaired in mammalian cells by two alternative pathways which involve either the replacement of one (short patch BER) or more nucleotides (long patch BER) at the lesion site.
