In enzymology a leucine-tRNA ligase (EC 6.1.1.4) is an enzyme that catalyzes the chemical reactionATP + L-leucine + tRNALeu AMP + diphosphate + L-leucyl-tRNALeuThe 3 substrates of this enzyme are ATP L-leucine and tRNA(Leu) whereas its 3 products are AMP diphosphate and L-leucyl-tRNA(Leu).This enzyme belongs to the family of ligases to be specific those forming carbon-oxygen bonds in aminoacyl-tRNA and related compounds.
