DNA-3-methyladenine glycosylase I

DNA-3-methyladenine glycosylase I (, deoxyribonucleate 3-methyladenine glycosidase I, 3-methyladenine DNA glycosylase I, DNA-3-methyladenine glycosidase I) is an enzyme with systematic name alkylated-DNA glycohydrolase (releasing methyladenine and methylguanine). This enzyme catalyses the following chemical reaction


 * Hydrolysis of alkylated DNA, releasing 3-methyladenine

This enzyme is involved in the removal of alkylated bases from DNA in Escherichia coli.
