In enzymology a lysine-tRNAPyl ligase (EC 6.1.1.25) is an enzyme that catalyzes the chemical reactionATP + L-lysine + tRNAPyl AMP + diphosphate + L-lysyl-tRNAPylThe 3 substrates of this enzyme are ATP L-lysine and tRNA(Pyl) whereas its 3 products are AMP diphosphate and L-lysyl-tRNA(Pyl).This enzyme belongs to the family of ligases to be specific those forming carbon-oxygen bonds in aminoacyl-tRNA and related compounds.
