|
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:0016740
|
transferase activity
|
Catalysis of the transfer of a group, e.g. a methyl group, glycosyl group, acyl group, phosphorus-containing, or other groups, from one compound (generally regarded as the donor) to another compound (generally regarded as the acceptor). Transferase is the systematic name for any enzyme of EC class 2. |
|
GO:0005488
|
binding
|
The selective, non-covalent, often stoichiometric, interaction of a molecule with one or more specific sites on another molecule. |
|
GO:0016755
|
aminoacyltransferase activity
|
Catalysis of the transfer of an amino-acyl group from one compound (donor) to another (acceptor). |
|
GO:0019787
|
ubiquitin-like protein transferase activity
|
Catalysis of the transfer of a ubiquitin-like from one protein to another via the reaction X-ULP + Y = Y-ULP + X, where both X-ULP and Y-ULP are covalent linkages. ULP represents a ubiquitin-like protein. |
|
GO:0140096
|
catalytic activity, acting on a protein
|
Catalytic activity that acts to modify a protein. |
|
GO:0016746
|
acyltransferase activity
|
Catalysis of the transfer of an acyl group from one compound (donor) to another (acceptor). |
|
GO:0005515
|
protein binding
|
Binding to a protein. |
|
GO:0098772
|
molecular function regulator activity
|
A molecular function regulator regulates the activity of its target via non-covalent binding that does not result in covalent modification to the target. Examples of molecular function regulators include regulatory subunits of multimeric enzymes and channels. Mechanisms of regulation include allosteric changes in the target and competitive inhibition. |
|
GO:0140677
|
molecular function activator activity
|
A molecular function regulator that activates or increases the activity of its target via non-covalent binding that does not result in covalent modification to the target. |
|
GO:0030234
|
enzyme regulator activity
|
Binds to and modulates the activity of an enzyme. |
|
GO:0004842
|
ubiquitin-protein transferase activity
|
Catalysis of the transfer of ubiquitin from one protein to another via the reaction X-Ub + Y = Y-Ub + X, where both X-Ub and Y-Ub are covalent linkages. |
|
GO:0008047
|
enzyme activator activity
|
Binds to and increases the activity of an enzyme. |
|
GO:0055106
|
ubiquitin-protein transferase regulator activity
|
Binds to and modulates the activity of a ubiquitin-protein transferase, an enzyme that catalyzes the covalent attachment of ubiquitin to lysine in a substrate protein. |
|
GO:0097027
|
ubiquitin-protein transferase activator activity
|
Binds to and increases the activity of a ubiquitin-protein transferase. |
