Protein

DNA-(apurinic or apyrimidinic site) lyase 2

Gene

apn2

Organism
Schizosaccharomyces pombe (strain 972 / ATCC 24843) (Fission yeast)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at protein leveli

Functioni

DNA repair enzyme that cleaves apurinic/apyrimidinic (AP) sites and removes 3'-blocking groups present at single strand breaks of damaged DNA. Provides the majority of the AP-endonuclease (APE) activity. Repairs phleomycin D1-induced DNA damage. Plays a role in oxidative damage repair.2 Publications

Catalytic activityi

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.1 PublicationPROSITE-ProRule annotation

Cofactori

Magnesium. Can also utilize manganese. Probably binds two magnesium or manganese ions per subunit (By similarity).By similarity
