Identification
Name: Valyl-tRNA synthetase
Synonyms:
  • Valine--tRNA ligase
  • ValRS
Gene Name: valS
Enzyme Class:
Biological Properties
General Function: Involved in nucleotide binding
Specific 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
Cellular Location: Cytoplasm

  • Valine, leucine and isoleucine biosynthesis pae00290
