Protein

DNA-(apurinic or apyrimidinic site) lyase

Gene

Apex1

Organism
Mus musculus (Mouse)
Status
Unreviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Initiates repair of AP sites in DNA by catalyzing hydrolytic incision of the phosphodiester backbone immediately adjacent to the damage, generating a single-strand break with 5'-deoxyribose phosphate and 3'-hydroxyl ends.UniRule annotation

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.UniRule annotation

Cofactori

Mg2+UniRule annotation, Mn2+UniRule annotationNote: Probably binds two magnesium or manganese ions per subunit.UniRule annotation
