General Information
Term DNA N-glycosylase activity ID (Ontology) GO:0019104 (Gene Ontology)
Definition Catalysis of the removal of damaged bases by cleaving the N-C1' glycosidic bond between the target damaged DNA base and the deoxyribose sugar. The reaction releases a free base and leaves an apurinic/apyrimidinic (AP) site.[ PubMed:11554296 ]
Also Known As"DNA glycosylase activity"
