Term Information

Accession
GO:0000703
Name
oxidized pyrimidine nucleobase lesion DNA N-glycosylase activity
Ontology
molecular_function
Synonyms
oxidized pyrimidine base lesion DNA N-glycosylase activity, endodeoxyribonuclease III, endonuclease III, endonuclease VIII activity, pyrimidine-specific oxidized base lesion DNA N-glycosylase activity, DNA glycosylase/AP-lyase, DNA glycosylase/beta-lyase, bifunctional DNA glycosylase
Alternate IDs
GO:0019004
Definition
Catalysis of the removal oxidized pyrimidine bases by cleaving the N-C1' glycosidic bond between the oxidized pyrimidine and the deoxyribose sugar. The reaction involves formation of a covalent enzyme-pyrimidine base intermediate. Release of the enzyme and free base by a beta-elimination or a beta, gamma-elimination mechanism results in the cleavage of the DNA backbone 3' of the apyrimidinic (AP) site. Source: PMID:11554296, GOC:elh
Comment
Consider also annotating to the molecular function term 'DNA-(apurinic or apyrimidinic site) lyase activity ; GO:0003906'.
