General annotation (Comments)

Function	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. Catalyzes the attachment of valine to tRNA(Val).
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.
Induction	By valine starvation. Is transcribed by itself and in an operon with folC. A GUC triplet (Val, the specifier codon) 190 nucleotides upstream of the initiator codon confers induction upon valaine starvation; replacing it with ACC (Thr) confers induction upon threonine starvation, replacing it with UAA (stop), renders the gene uninducible. Negatively regulates its own transcription; this depends on the presence of the GUC specifier codon.
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.
Disruption phenotype	Cells lacking this gene grow normally, suggesting there is a second functional gene with valine-tRNA synthetase activity in B.subtilis.
Sequence similarities	Belongs to the class-I aminoacyl-tRNA synthetase family. ValS type 1 subfamily.
