Comments:
-!- FUNCTION: Endonuclease IV plays a role in DNA repair. It cleaves
phosphodiester bonds at apurinic or apyrimidinic sites (AP sites)
to produce new 5' ends that are base-free deoxyribose 5-phosphate
residues. It preferentially attacks modified AP sites created by
bleomycin and neocarzinostatin (By similarity).
-!- CATALYTIC ACTIVITY: Endonucleolytic cleavage to 5'-
phosphooligonucleotide end-products.
-!- COFACTOR: Binds 3 zinc ions (By similarity).
-!- SIMILARITY: Belongs to the AP endonuclease 2 family.
