DNA-(Apurinic or Apyrimidinic Site) Lyase
Apurine Apyrimidine Endonuclease
Apurinic DNA Endonuclease
DNA Endonuclease, Apurinic
DNA Lyase (Apurinic or Apyrimidinic)
Endodeoxyribonuclease (Apurinic or Apyrimidinic)
Endonuclease, Apurinic DNA
A DNA repair enzyme that catalyses the excision of ribose residues at apurinic and apyrimidinic DNA sites that can result from the action of DNA GLYCOSYLASES. The enzyme catalyzes a beta-elimination reaction in which the C-O-P bond 3' to the apurinic or apyrimidinic site in DNA is broken, leaving a 3'-terminal unsaturated sugar and a product with a terminal 5'-phosphate. This enzyme was previously listed under EC 188.8.131.52.
