CC   -!- FUNCTION: Catalyzes the attachment of valine to tRNA(Val). As ValRS can
CC       inadvertently accommodate and process structurally similar amino acids
CC       such as threonine, to avoid such errors, it has a 'posttransfer'
CC       editing activity that hydrolyzes mischarged Thr-tRNA(Val) in a tRNA-
CC       dependent manner. {ECO:0000255|HAMAP-Rule:MF_02004}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=ATP + L-valine + tRNA(Val) = AMP + diphosphate + L-valyl-
CC         tRNA(Val); Xref=Rhea:RHEA:10704, Rhea:RHEA-COMP:9672, Rhea:RHEA-

CC         ChEBI:CHEBI:78442, ChEBI:CHEBI:78537, ChEBI:CHEBI:456215; EC=6.1.1.9;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_02004};
CC   -!- SUBUNIT: Monomer. {ECO:0000255|HAMAP-Rule:MF_02004}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_02004}.
CC   -!- DOMAIN: ValRS has two distinct active sites: one for aminoacylation and
CC       one for editing. The misactivated threonine is translocated from the
CC       active site to the editing site. {ECO:0000255|HAMAP-Rule:MF_02004}.
CC   -!- DOMAIN: The C-terminal coiled-coil domain is crucial for aminoacylation
CC       activity. {ECO:0000255|HAMAP-Rule:MF_02004}.
CC   -!- SIMILARITY: Belongs to the class-I aminoacyl-tRNA synthetase family.
CC       ValS type 1 subfamily. {ECO:0000255|HAMAP-Rule:MF_02004}.
