|
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:0016874
|
ligase activity
|
Catalysis of the joining of two molecules, or two groups within a single molecule, using the energy from the hydrolysis of ATP, a similar triphosphate, or a pH gradient. |
|
GO:0016877
|
ligase activity, forming carbon-sulfur bonds
|
Catalysis of the joining of two molecules via a carbon-sulfur bond, with the concomitant hydrolysis of the diphosphate bond in ATP or a similar triphosphate. |
|
GO:0016405
|
CoA-ligase activity
|
Catalysis of the reaction: substrate + ATP + CoASH = AMP + diphosphate + substrate-CoA. |
|
GO:0003987
|
acetate-CoA ligase activity
|
Catalysis of the reaction: ATP + acetate + CoA = AMP + diphosphate + acetyl-CoA. |
|
GO:0016878
|
acid-thiol ligase activity
|
Catalysis of the joining of an acid and a thiol via a carbon-sulfur bond, with the concomitant hydrolysis of the diphosphate bond in ATP or a similar triphosphate. |
