|
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:0004812
|
aminoacyl-tRNA ligase activity
|
Catalysis of the formation of aminoacyl-tRNA from ATP, amino acid, and tRNA with the release of diphosphate and AMP. |
|
GO:0016874
|
ligase activity
|
Catalysis of the joining of two substances, or two groups within a single molecule, with the concomitant hydrolysis of the diphosphate bond in ATP or a similar triphosphate. |
|
GO:0016876
|
ligase activity, forming aminoacyl-tRNA and related compounds
|
Catalysis of the joining of an amino acid and a nucleic acid (usually tRNA) or poly(ribitol phosphate), with the concomitant hydrolysis of the diphosphate bond in ATP or a similar triphosphate. The reaction forms an aminoacyl-tRNA or a related compound. |
|
GO:0004827
|
proline-tRNA ligase activity
|
Catalysis of the reaction: ATP + L-proline + tRNA(Pro) = AMP + diphosphate + L-prolyl-tRNA(Pro). |
|
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:0016875
|
ligase activity, forming carbon-oxygen bonds
|
Catalysis of the joining of two molecules via a carbon-oxygen bond, with the concomitant hydrolysis of the diphosphate bond in ATP or a similar triphosphate. |
