1 GO annotations of cellular component
| Name | Definition |
|---|---|
| cytosol | The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes. |
4 GO annotations of molecular function
| Name | Definition |
|---|---|
| aminoacyl-tRNA editing activity | The hydrolysis of an incorrectly aminoacylated tRNA. |
| ATP binding | Binding to ATP, adenosine 5'-triphosphate, a universally important coenzyme and enzyme regulator. |
| magnesium ion binding | Binding to a magnesium (Mg) ion. |
| valine-tRNA ligase activity | Catalysis of the reaction: L-valine + ATP + tRNA(Val) = L-valyl-tRNA(Val) + AMP + diphosphate + 2 H(+). |
3 GO annotations of biological process
| Name | Definition |
|---|---|
| cytosolic valyl-tRNA aminoacylation | The process of coupling valine to valyl-tRNA in the cytosol, catalyzed by valyl-tRNA synthetase. In tRNA aminoacylation, the amino acid is first activated by linkage to AMP and then transferred to either the 2'- or the 3'-hydroxyl group of the 3'-adenosine residue of the tRNA. |
| positive regulation of translational fidelity | Any process that increases the ability of the translational apparatus to interpret the genetic code. |
| valyl-tRNA aminoacylation | The process of coupling valine to valyl-tRNA, catalyzed by valyl-tRNA synthetase. The valyl-tRNA synthetase is a class-I synthetase. The activated amino acid is transferred to the 2'-OH group of a valine-accetping tRNA. The 2'-O-aminoacyl-tRNA will ultimately migrate to the 3' position via transesterification. |
