|
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:0016788
|
hydrolase activity, acting on ester bonds
|
Catalysis of the hydrolysis of any ester bond. |
|
GO:0042578
|
phosphoric ester hydrolase activity
|
Catalysis of the reaction: RPO-R' + H2O = RPOOH + R'H. This reaction is the hydrolysis of any phosphoric ester bond, any ester formed from orthophosphoric acid, O=P(OH)3. |
|
GO:0008081
|
phosphoric diester hydrolase activity
|
Catalysis of the hydrolysis of a phosphodiester to give a phosphomonoester and a free hydroxyl group. |
|
GO:0016298
|
lipase activity
|
Catalysis of the hydrolysis of a lipid. |
|
GO:0004620
|
phospholipase activity
|
Catalysis of the hydrolysis of a glycerophospholipid. |
|
GO:0004630
|
phospholipase D activity
|
Catalysis of the reaction: a phosphatidylcholine + H2O = choline + a phosphatidate. |
|
GO:0004621
|
glycosylphosphatidylinositol phospholipase D activity
|
Catalysis of the reaction: glycoprotein phosphatidylinositol + H2O = phosphatidate + glycoprotein inositol. |
