Protein

Valine--tRNA ligase

Gene

valS

Organism
Pyrococcus horikoshii (strain ATCC 700860 / DSM 12428 / JCM 9974 / NBRC 100139 / OT-3)
Status
Reviewed-Annotation score: -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

Sequence similaritiesi

Belongs to the class-I aminoacyl-tRNA synthetase family. ValS type 2 subfamily.UniRule annotation
