General Information
Term class I DNA-(apurinic or apyrimidinic site) endonuclease activity ID (Ontology) GO:0140078 (Gene Ontology)
Definition Catalysis of the cleavage of an AP site 3' of the baseless site by a beta-lyase mechanism, leaving an unsaturated aldehyde, termed a 3'-(4-hydroxy-5-phospho-2-pentenal) residue, and a 5'-phosphate.[ PubMed:1698278 ]
Also Known As "AP site-DNA 5'-phosphomonoester-lyase activity" ; "class I DNA-(apurinic or apyrimidinic site) lyase activity" ; "DNA-(apurinic or apyrimidinic site) 5'-phosphomonoester-lyase activity" (for all, see Synonyms field below)
