|
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:0016301
|
kinase activity
|
Catalysis of the transfer of a phosphate group, usually from ATP, to a substrate molecule. |
|
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:0016772
|
transferase activity, transferring phosphorus-containing groups
|
Catalysis of the transfer of a phosphorus-containing group from one compound (donor) to another (acceptor). |
|
GO:0019205
|
nucleobase-containing compound kinase activity
|
Catalysis of the transfer of a phosphate group, usually from ATP or GTP, to a nucleobase, nucleoside, nucleotide or polynucleotide substrate. |
|
GO:0016776
|
phosphotransferase activity, phosphate group as acceptor
|
Catalysis of the transfer of a phosphorus-containing group from one compound (donor) to a phosphate group (acceptor). |
|
GO:0004550
|
nucleoside diphosphate kinase activity
|
Catalysis of the reaction: ATP + nucleoside diphosphate = ADP + nucleoside triphosphate. |
|
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. |
