In enzymology a lysine-tRNA ligase (EC 6.1.1.6) is an enzyme that catalyzes the chemical reactionATP + L-lysine + tRNALys AMP + diphosphate + L-lysyl-tRNALysThe 3 substrates of this enzyme are ATP L-lysine and tRNA(Lys) whereas its 3 products are AMP diphosphate and L-lysyl-tRNA(Lys).This enzyme belongs to the family of ligases to be specific those forming carbon-oxygen bonds in aminoacyl-tRNA and related compounds.
