|
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:0016817
|
hydrolase activity, acting on acid anhydrides
|
Catalysis of the hydrolysis of any acid anhydride. |
GO:0016818
|
hydrolase activity, acting on acid anhydrides, in phosphorus-containing anhydrides
|
Catalysis of the hydrolysis of any acid anhydride which contains phosphorus. |
GO:0016462
|
pyrophosphatase activity
|
Catalysis of the hydrolysis of a pyrophosphate bond (diphosphate bond) between two phosphate groups. |
GO:0017111
|
ribonucleoside triphosphate phosphatase activity
|
Catalysis of the reaction: a ribonucleoside triphosphate + H2O = a ribonucleoside diphosphate + H+ + phosphate. |
GO:0016887
|
ATP hydrolysis activity
|
Catalysis of the reaction: ATP + H2O = ADP + H+ phosphate. ATP hydrolysis is used in some reactions as an energy source, for example to catalyze a reaction or drive transport against a concentration gradient. |
GO:0140657
|
ATP-dependent activity
|
A molecular function characterized by the coupling of ATP hydrolysis to other steps of a reaction mechanism to make the reaction energetically favorable, for example to catalyze a reaction or drive transport against a concentration gradient. |
GO:0003774
|
cytoskeletal motor activity
|
Generation of force resulting in movement, for example along a microfilament or microtubule, or in torque resulting in membrane scission or rotation of a flagellum. The energy required is obtained either from the hydrolysis of a nucleoside triphosphate or by an electrochemical proton gradient (proton-motive force). |
GO:0120544
|
polypeptide conformation or assembly isomerase activity
|
Catalysis of a reaction that alters the conformation or assembly of a polypeptide. |
GO:0016853
|
isomerase activity
|
Catalysis of the geometric or structural changes within one molecule. Isomerase is the systematic name for any enzyme of EC class 5. |
GO:0120543
|
macromolecular conformation isomerase activity
|
Catalysis of a reaction that alters the macromolecular conformation of a molecule. |
GO:0003777
|
microtubule motor activity
|
A motor activity that generates movement along a microtubule, driven by ATP hydrolysis. |
