PROSITE; PS51435; AP_NUCLEASE_F1_4 |
Name | AP endonucleases family 1 |
Function | Exonuclease III and AP endonuclease 1 related enzymes play a role in DNA repair. These nucleases cleave phosphodiester bonds at apurinic or apyrimidinic sites (AP sites) to produce new 5'-ends that are base-free deoxyribose 5-phosphate residues. |
Scope(s) |
Eukaryota Bacteria |
Example(s) | P28352 (APEX1_MOUSE); P44318 (EX3_HAEIN); |
