In enzymology an isoleucine-tRNA ligase (EC 6.1.1.5) is an enzyme that catalyzes the chemical reactionATP + L-isoleucine + tRNAIle AMP + diphosphate + L-isoleucyl-tRNAIleThe 3 substrates of this enzyme are ATP L-isoleucine and tRNA(Ile) whereas its 3 products are AMP diphosphate and L-isoleucyl-tRNA(Ile).This enzyme belongs to the family of ligases to be specific those forming carbon-oxygen bonds in aminoacyl-tRNA and related compounds.
