|
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: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:0016811
|
hydrolase activity, acting on carbon-nitrogen (but not peptide) bonds, in linear amides
|
Catalysis of the hydrolysis of any non-peptide carbon-nitrogen bond in a linear amide. |
|
GO:0019213
|
deacetylase activity
|
Catalysis of the hydrolysis of an acetyl group from a substrate molecule. |
|
GO:0000225
|
N-acetylglucosaminylphosphatidylinositol deacetylase activity
|
Catalysis of the reaction: N-acetyl-D-glucosaminylphosphatidylinositol + H2O = D-glucosaminylphosphatidylinositol + acetate. This reaction is the second step of the biosynthesis of glycosylphosphatidylinositol (GPI), used to anchor various eukaryotic proteins to the cell-surface membrane. |
|
GO:0160215
|
deacylase activity
|
Catalysis of the reaction: R-CO-X + H2O = R-COOH + HX, hydrolysis of an acyl group or groups from a substrate molecule. |
