Valine—tRNA ligase
In enzymology, a valine-tRNA ligase is an enzyme that catalyzes the chemical reaction
The 3 substrates of this enzyme are ATP, L-valine, and tRNA, whereas its 3 products are AMP, diphosphate, and L-valyl-tRNA.
This enzyme belongs to the family of ligases, to be specific those forming carbon-oxygen bonds in aminoacyl-tRNA and related compounds. The systematic name of this enzyme class is L-valine:tRNAVal ligase . Other names in common use include valyl-tRNA synthetase, valyl-transfer ribonucleate synthetase, valyl-transfer RNA synthetase, valyl-transfer ribonucleic acid synthetase, valine transfer ribonucleate ligase, and valine translase. This enzyme participates in valine, leucine and isoleucine biosynthesis and aminoacyl-trna biosynthesis.As of late 2007, 5 structures have been solved for this class of enzymes, with PDB accession codes,,,, and.
