RL Submitted (OCT-2008) to the EMBL/GenBank/DDBJ databases.
CC -!- FUNCTION: Endonuclease IV plays a role in DNA repair. It cleaves
CC phosphodiester bonds at apurinic or apyrimidinic (AP) sites, generating
CC a 3'-hydroxyl group and a 5'-terminal sugar phosphate.
CC {ECO:0000255|HAMAP-Rule:MF_00152}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=Endonucleolytic cleavage to 5'-phosphooligonucleotide end-
CC products.; EC=3.1.21.2; Evidence={ECO:0000255|HAMAP-Rule:MF_00152};
CC -!- COFACTOR:
CC Name=Zn(2+); Xref=ChEBI:CHEBI:29105;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_00152};
CC Note=Binds 3 Zn(2+) ions. {ECO:0000255|HAMAP-Rule:MF_00152};
CC -!- SIMILARITY: Belongs to the AP endonuclease 2 family.
CC {ECO:0000255|HAMAP-Rule:MF_00152}.
