2 GO annotations of cellular component

Name Definition
nucleus A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.
protein-DNA complex A macromolecular complex containing both protein and DNA molecules.

7 GO annotations of molecular function

Name Definition
alkylated DNA binding Binding to an alkylated residue in DNA.
alkylbase DNA N-glycosylase activity Catalysis of the reaction: DNA with alkylated base + H2O = DNA with abasic site + alkylated base. This reaction is the hydrolysis of DNA by cleavage of the N-C1' glycosidic bond between the target damaged DNA base and the deoxyribose sugar to remove an alkylated base, leaving an apyrimidinic or apurinic site.
damaged DNA binding Binding to damaged DNA.
DNA-3-methyladenine glycosylase 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.
DNA-3-methylguanine glycosylase activity 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.
DNA-7-methyladenine glycosylase activity Catalysis of the reaction: DNA containing 7-methyladenine + H2O = DNA with abasic site + 7-methyladenine. This reaction is the hydrolysis of DNA by cleavage of the N-C1' glycosidic bond between the damaged DNA 7-methyladenine and the deoxyribose sugar to remove the 7-methyladenine, leaving an abasic site.
DNA-7-methylguanine glycosylase activity Catalysis of the reaction: DNA containing 7-methylguanine + H2O = DNA with abasic site + 7-methylguanine. This reaction is the hydrolysis of DNA by cleavage of the N-C1' glycosidic bond between the damaged DNA 7-methylguanine and the deoxyribose sugar to remove the 7-methylguanine, leaving an abasic site.

2 GO annotations of biological process

Name Definition
base-excision repair, AP site formation The formation of an AP site, a deoxyribose sugar with a missing base, by DNA glycosylase which recognizes an altered base in DNA and catalyzes its hydrolytic removal. This sugar phosphate is the substrate recognized by the AP endonuclease, which cuts the DNA phosphodiester backbone at the 5' side of the altered site to leave a gap which is subsequently repaired.
DNA dealkylation involved in DNA repair The repair of alkylation damage, e.g. the removal of the alkyl group at the O6-position of guanine by O6-alkylguanine-DNA alkyltransferase (AGT).
