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:0016787
|
hydrolase activity
|
Catalysis of the hydrolysis of various bonds, e.g. C-O, C-N, C-C, phosphoric anhydride bonds, etc. |
|
GO:0004553
|
hydrolase activity, hydrolyzing O-glycosyl compounds
|
Catalysis of the hydrolysis of any O-glycosyl bond. |
|
GO:0016798
|
hydrolase activity, acting on glycosyl bonds
|
Catalysis of the hydrolysis of any glycosyl bond. |
|
GO:0065007
|
biological regulation
|
Any process that modulates a measurable attribute of any biological process, quality or function. |
|
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:0015925
|
galactosidase activity
|
Catalysis of the hydrolysis of galactosyl compounds, substances containing a group derived from a cyclic form of galactose or a galactose derivative. |
|
GO:0004565
|
beta-galactosidase activity
|
Catalysis of the hydrolysis of terminal, non-reducing beta-D-galactose residues in beta-D-galactosides. |
|
GO:0044092
|
negative regulation of molecular function
|
Any process that stops or reduces the rate or extent of a molecular function, an elemental biological activity occurring at the molecular level, such as catalysis or binding. |
|
GO:0043086
|
negative regulation of catalytic activity
|
Any process that stops or reduces the activity of an enzyme. |
|
GO:0051346
|
negative regulation of hydrolase activity
|
Any process that stops or reduces the rate of hydrolase activity, the catalysis of the hydrolysis of various bonds. |
|
GO:0051336
|
regulation of hydrolase activity
|
Any process that modulates the frequency, rate or extent of hydrolase activity, the catalysis of the hydrolysis of various bonds, e.g. C-O, C-N, C-C, phosphoric anhydride bonds, etc. Hydrolase is the systematic name for any enzyme of EC class 3. |
|
GO:1903770
|
negative regulation of beta-galactosidase activity
|
Any process that stops, prevents or reduces the frequency, rate or extent of beta-galactosidase activity. |
