|
catalytic activity
|
Catalysis of a biochemical reaction at physiological temperatures. In biologically catalyzed reactions, the reactants are known as substrates, and the catalysts are naturally occurring macromolecular substances known as enzymes. Enzymes possess specific binding sites for substrates, and are usually composed wholly or largely of protein, but RNA that has catalytic activity (ribozyme) is often also regarded as enzymatic. |

GO:0016798
|
hydrolase activity, acting on glycosyl bonds
|
Catalysis of the hydrolysis of any glycosyl bond. |
|
GO:0016787
|
hydrolase activity
|
Catalysis of the hydrolysis of various bonds, e.g. C-O, C-N, C-C, phosphoric anhydride bonds, etc. Hydrolase is the systematic name for any enzyme of EC class 3. |
|
GO:0008725
|
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. |
|
GO:0016799
|
hydrolase activity, hydrolyzing N-glycosyl compounds
|
Catalysis of the hydrolysis of any N-glycosyl bond. |
|
GO:0003674
|
molecular_function
|
Elemental activities, such as catalysis or binding, describing the actions of a gene product at the molecular level. A given gene product may exhibit one or more molecular functions. |
|
GO:0019104
|
DNA N-glycosylase activity
|
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. |
|
GO:0003905
|
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. |
|
GO:0043733
|
DNA-3-methylbase glycosylase activity
|
Catalysis of the reaction: DNA containing 3-methylbase + H2O = DNA with abasic site + 3-methylbase. This reaction is the hydrolysis of DNA by cleavage of the N-C1' glycosidic bond between the damaged DNA 3-methylpurine or 3-methylpyrimidine base and the deoxyribose sugar to remove the methylated base, leaving an apurinic or apyrimidinic site. |
