biological_process
|
A biological process is the execution of a genetically-encoded biological module or program. It consists of all the steps required to achieve the specific biological objective of the module. A biological process is accomplished by a particular set of molecular functions carried out by specific gene products (or macromolecular complexes), often in a highly regulated manner and in a particular temporal sequence. |
|
GO:0003674
|
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:0065007
|
biological regulation
|
Any process that modulates a measurable attribute of any biological process, quality or function. |
|
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:0050790
|
regulation of catalytic activity
|
Any process that modulates the activity of an enzyme. |
|
GO:0065009
|
regulation of molecular function
|
Any process that modulates the frequency, rate or extent of a molecular function, an elemental biological activity occurring at the molecular level, such as catalysis or binding. |
|
GO:0016879
|
ligase activity, forming carbon-nitrogen bonds
|
Catalysis of the joining of two molecules, or two groups within a single molecule, via a carbon-nitrogen bond, with the concomitant hydrolysis of the diphosphate bond in ATP or a similar triphosphate. |
|
GO:0016881
|
acid-amino acid ligase activity
|
Catalysis of the ligation of an acid to an amino acid via a carbon-nitrogen bond, with the concomitant hydrolysis of the diphosphate bond in ATP or a similar triphosphate. |
|
GO:0004357
|
glutamate-cysteine ligase activity
|
Catalysis of the reaction: L-cysteine + L-glutamate + ATP = L-gamma-glutamyl-L-cysteine + ADP + 2 H+ + phosphate. |
|
GO:0043085
|
positive regulation of catalytic activity
|
Any process that activates or increases the activity of an enzyme. |
|
GO:0044093
|
positive regulation of molecular function
|
Any process that activates or increases the rate or extent of a molecular function, an elemental biological activity occurring at the molecular level, such as catalysis or binding. |
|
GO:0051351
|
positive regulation of ligase activity
|
Any process that activates or increases the frequency, rate or extent of ligase activity, the catalysis of the ligation of two substances with concomitant breaking of a diphosphate linkage, usually in a nucleoside triphosphate. |
|
GO:0035229
|
positive regulation of glutamate-cysteine ligase activity
|
Any process that activates or increases the activity of glutamate-cysteine ligase, typically by lowering its sensitivity to inhibition by glutathione and by increasing its affinity for glutamate. |
