Protein existenceInferred from homology

General annotation (Comments)

Function

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 By similarity. HAMAP MF_02005

Catalytic activity

ATP + L-valine + tRNA(Val) = AMP + diphosphate + L-valyl-tRNA(Val). HAMAP MF_02005

Subcellular location

Cytoplasm By similarity HAMAP MF_02005.

Domain

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 By similarity. HAMAP MF_02005

Sequence similarities

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