Term Name:	purine-specific mismatch base pair DNA N-glycosylase activity
Synonyms:	A/G-specific adenine DNA glycosylase activity
Definition:	Catalysis of the removal of purines present in mismatches, especially opposite oxidized purines, 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 (AP) site.
