Protein existence	Inferred 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.
Catalytic activity	ATP + L-valine + tRNA(Val) = AMP + diphosphate + L-valyl-tRNA(Val). HAMAP MF_02004
Subunit structure	Monomer By similarity.
Subcellular location	Cytoplasm By similarity.
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. The C-terminal coiled-coil domain is crucial for aminoacylation activity By similarity.
Sequence similarities	Belongs to the class-I aminoacyl-tRNA synthetase family. ValS type 1 subfamily.
