|
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: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:0008168
|
methyltransferase activity
|
Catalysis of the transfer of a methyl group to an acceptor molecule. |
GO:0008757
|
S-adenosylmethionine-dependent methyltransferase activity
|
Catalysis of the transfer of a methyl group from S-adenosyl-L-methionine to a substrate. |
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:0032259
|
methylation
|
The process in which a methyl group is covalently attached to a molecule. |
GO:0030750
|
putrescine N-methyltransferase activity
|
Catalysis of the reaction: S-adenosyl-L-methionine + putrescine = N-methylputrescine + S-adenosyl-L-homocysteine + H(+). |
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:0016741
|
transferase activity, transferring one-carbon groups
|
Catalysis of the transfer of a one-carbon group from one compound (donor) to another (acceptor). |
