Details for DNA-3-methylguanine glycosylase activity

3.2.2.21

Gene ontology ID

GO:0052822

Definition

Catalysis of the reaction: DNA containing 3-methylguanine + H2O = DNA with abasic site + 3-methylguanine. This reaction is the hydrolysis of DNA by cleavage of the N-C1' glycosidic bond between the damaged DNA 3-methylguanine and the deoxyribose sugar to remove the 3-methylguanine, leaving an abasic site

Synonyms

1. 3-methylguanine DNA glycosylase I
2. alkylated-DNA glycohydrolase (releasing methyladenine and methylguanine)
3. deoxyribonucleate 3-methylguanine glycosidase I
4. DNA glycosidase I activity
