|
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: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:0016747
|
acyltransferase activity, transferring groups other than amino-acyl groups
|
Catalysis of the transfer of an acyl group, other than amino-acyl, from one compound (donor) to another (acceptor). |
|
GO:0016410
|
N-acyltransferase activity
|
Catalysis of the transfer of an acyl group to a nitrogen atom on the acceptor molecule. |
|
GO:0016407
|
acetyltransferase activity
|
Catalysis of the transfer of an acetyl group to an acceptor molecule. |
|
GO:0008080
|
N-acetyltransferase activity
|
Catalysis of the transfer of an acetyl group to a nitrogen atom on the acceptor molecule. |
|
GO:0061733
|
protein-lysine-acetyltransferase activity
|
Catalysis of the reaction: acetyl-CoA + lysine in peptide = CoA + N-acetyl-lysine-peptide. The acetyl group is transferred to the nitrogen atom at position 6 of the lysine residue in the protein. |
|
GO:0034212
|
protein N-acetyltransferase activity
|
Catalysis of the acetylation of an amino acid residue of a peptide or protein, according to the reaction: acetyl-CoA + peptide = CoA + N-acetylpeptide. |
