|
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. Hydrolase is the systematic name for any enzyme of EC class 3. |
|
GO:0005515
|
protein binding
|
Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules). |
|
GO:0005488
|
binding
|
The selective, non-covalent, often stoichiometric, interaction of a molecule with one or more specific sites on another molecule. |
|
GO:0004553
|
hydrolase activity, hydrolyzing O-glycosyl compounds
|
Catalysis of the hydrolysis of any O-glycosyl bond. |
|
GO:0008152
|
metabolic process
|
The chemical reactions and pathways, including anabolism and catabolism, by which living organisms transform chemical substances. Metabolic processes typically transform small molecules, but also include macromolecular processes such as DNA repair and replication, and protein synthesis and degradation. |
|
GO:0004857

|
GO:0030234
|
enzyme regulator activity
|
Binds to and modulates the activity of an enzyme. |
|
GO:0016798
|
hydrolase activity, acting on glycosyl bonds
|
Catalysis of the hydrolysis of any glycosyl bond. |
|
GO:0004556

Catalysis of the endohydrolysis of (1->4)-alpha-D-glucosidic linkages in polysaccharides containing three or more alpha-(1->4)-linked D-glucose units. |
|
GO:0050790
|
regulation of catalytic activity
|
Any process that modulates the activity of an enzyme. |
|
GO:0043086
|
negative regulation of catalytic activity
|
Any process that stops or reduces the activity of an enzyme. |
|
GO:0015066
|
alpha-amylase inhibitor activity
|
Stops, prevents or reduces the activity of alpha-amylase. |
|
GO:0008150
|
biological_process
|
Any process specifically pertinent to the functioning of integrated living units: cells, tissues, organs, and organisms. A process is a collection of molecular events with a defined beginning and end. |
|
GO:0003674
|
molecular_function
|
Elemental activities, such as catalysis or binding, describing the actions of a gene product at the molecular level. A given gene product may exhibit one or more molecular functions. |
|
GO:0065007
|
biological regulation
|
Any process that modulates a measurable attribute of any biological process, quality or function. |
|
GO:0050789
|
regulation of biological process
|
Any process that modulates the frequency, rate or extent of a biological process. Biological processes are regulated by many means; examples include the control of gene expression, protein modification or interaction with a protein or substrate molecule. |
|
GO:0019222
|
regulation of metabolic process
|
Any process that modulates the frequency, rate or extent of the chemical reactions and pathways within a cell or an organism. |
|
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:0044092
|
negative regulation of molecular function
