Protein

Valine--tRNA ligase

Gene

valS

Organism
Mycoplasma genitalium (strain ATCC 33530 / G-37 / NCTC 10195)
Status
Reviewed - Annotation score: 3 out of 5- Protein inferred from homologyi

Functioni

Catalyzes the attachment of valine to tRNA(Val). As ValRS can inadvertently accommodate and process structurally similar amino acids such as threonine, to avoid such errors, it has a "posttransfer" editing activity that hydrolyzes mischarged Thr-tRNA(Val) in a tRNA-dependent manner.UniRule annotation

Catalytic activityi

ATP + L-valine + tRNA(Val) = AMP + diphosphate + L-valyl-tRNA(Val).UniRule annotation

Domaini

ValRS has two distinct active sites: one for aminoacylation and one for editing. The misactivated threonine is translocated from the active site to the editing site.UniRule annotation
The C-terminal coiled-coil domain is crucial for aminoacylation activity.UniRule annotation

Sequence similaritiesi

Belongs to the class-I aminoacyl-tRNA synthetase family. ValS type 1 subfamily.UniRule annotation
