|
molecular_function
|
A molecular process that can be carried out by the action of a single macromolecular machine, usually via direct physical interactions with other molecular entities. Function in this sense denotes an action, or activity, that a gene product (or a complex) performs. |
|
GO:0003824
|
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:0016787
|
hydrolase activity
|
Catalysis of the hydrolysis of various bonds, e.g. C-O, C-N, C-C, phosphoric anhydride bonds, etc. |
|
GO:0016814
|
hydrolase activity, acting on carbon-nitrogen (but not peptide) bonds, in cyclic amidines
|
Catalysis of the hydrolysis of any non-peptide carbon-nitrogen bond in a cyclic amidine, a compound of the form R-C(=NH)-NH2. |
|
GO:0019239
|
deaminase activity
|
Catalysis of the removal of an amino group from a substrate, producing a substituted or nonsubstituted ammonia (NH3/NH2R). |
|
GO:0016810
|
hydrolase activity, acting on carbon-nitrogen (but not peptide) bonds
|
Catalysis of the hydrolysis of any carbon-nitrogen bond, C-N, with the exception of peptide bonds. |
|
GO:0047623
|
adenosine-phosphate deaminase activity
|
Catalysis of the reaction: an adenosine-phosphate + H20 = an inosine phosphate + NH3. Catalyzes the deamination of AMP, ADP or ATP. |
|
GO:0003876
|
AMP deaminase activity
|
Catalysis of the reaction: AMP + H2O = IMP + NH3. |
