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-Rule MF_02004

Catalytic activity

ATP + L-valine + tRNA(Val) = AMP + diphosphate + L-valyl-tRNA(Val). HAMAP-Rule 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. HAMAP-Rule MF_02004

The C-terminal coiled-coil domain is crucial for aminoacylation activity By similarity. HAMAP-Rule MF_02004

Sequence similarities

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