General annotation (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. HAMAP-Rule MF_00152

Catalytic activity

Endonucleolytic cleavage to 5'-phosphooligonucleotide end-products. HAMAP-Rule MF_00152

Cofactor

Binds 3 zinc ions By similarity. HAMAP-Rule MF_00152

Sequence similarities

Belongs to the AP endonuclease 2 family.
