Comments
[?]
| FUNCTION | Endonuclease IV plays a role in DNA repair. It cleaves phosphodiester bonds at apurinic or apyrimidinic (AP) sites, generating a 3'-hydroxyl group and a 5'-terminal sugar phosphate. |
| CATALYTIC ACTIVITY | Reaction=Endonucleolytic cleavage to 5'-phosphooligonucleotide end- products.; EC=3.1.21.2; |
| COFACTOR | Name=Zn(2+); Xref=ChEBI:CHEBI:29105; Note=Binds 3 Zn(2+) ions.; |
| SIMILARITY | Belongs to the AP endonuclease 2 family. |
