DNA-3-methyladenine glycosylase activity https://github.com/geneontology/go-ontology/issues/28183 https://github.com/geneontology/go-ontology/issues/28514 MetaCyc:RXN0-5189 deoxyribonucleate 3-methyladenine glycosidase I DNA-3-methyladenine glycosidase I activity DNA-3-methyladenine glycosylase I activity Catalysis of the reaction: DNA containing 3-methyladenine + H2O = DNA with abasic site + 3-methyladenine. This reaction is the hydrolysis of DNA by cleavage of the N-C1' glycosidic bond between the damaged DNA 3-methyladenine and the deoxyribose sugar to remove the 3-methyladenine, leaving an abasic site. 3-methyladenine DNA glycosylase I DNA glycosidase I activity molecular_function EC:3.2.2.20 GO:0008725 DNA-3-methylbase glycosylase activity
