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. Catalysis of the hydrolysis of alkylated DNA; recognizes and removes alkylated purines and pyrimidines 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 or apyrimidinic (AP) site. Enzyme has broad substrate specificity, being able to recognize alkylpurines, alkylpyrimidines or ethenopurines. Catalysis of the hydrolysis of alkylated DNA; recognizes and removes both N-3- and N-7-methyl 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.
