General annotation (Comments)

Function

DNA repair enzyme that cleaves apurinic/apyrimidinic (AP) sites and removes 3'-blocking groups present at single strand breaks of damaged DNA. APN1 accounts for > 97% of both apurinic/ apyrimidinic (AP) lyase and DNA 3'-repair diesterase activities.

Catalytic activity

The C-O-P bond 3' to the apurinic or apyrimidinic site in DNA is broken by a beta-elimination reaction, leaving a 3'-terminal unsaturated sugar and a product with a terminal 5'-phosphate.

Cofactor

Binds 3 zinc ions.

Subunit structure

Monomer.

Subcellular location

Nucleus.

Miscellaneous

Present with 7250 molecules/cell in log phase SD medium.

Sequence similarities

Belongs to the AP endonuclease 2 family.
