MeSH Heading: DNA-(Apurinic or Apyrimidinic Site) Lyase
Tree Number(s): D08.811.074.750; D08.811.520.241.225
Unique ID: D043603
RDF Unique Identifier: http://id.nlm.nih.gov/mesh/D043603
Scope Note: 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 3.1.25.2.
Entry Term(s): AP Endonuclease; AP Lyase; Apurine-Apyrimidine Endonuclease; Apurinic DNA Endonuclease; Apurinic Endonuclease; DNA Lyase (Apurinic or Apyrimidinic); Endodeoxyribonuclease (Apurinic or Apyrimidinic)
Previous Indexing: Carbon-Oxygen Lyases (1978-2003)
