purine-specific mismatch base pair DNA N-glycosylase activity

id: GO:0000701
name: purine-specific mismatch base pair DNA N-glycosylase activity
namespace: molecular_function
type: go
obsolete: False

Description: 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.
