General rule information
[?]
| Accession | PRU00764 |
| Dates | 2-MAR-2009 (Created) 2-MAR-2020 (Last updated, Version 8) |
| Data class | Domain |
| Predictors | 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. |
