In enzymology a phenylalanine-tRNA ligase (EC 6.1.1.20) is an enzyme that catalyzes the chemical reactionATP + L-phenylalanine + tRNAPhe AMP + diphosphate + L-phenylalanyl-tRNAPheThe 3 substrates of this enzyme are ATP L-phenylalanine and tRNA(Phe) whereas its 3 products are AMP diphosphate and L-phenylalanyl-tRNA(Phe).This enzyme belongs to the family of ligases to be specific those forming carbon-oxygen bonds in aminoacyl-tRNA and related compounds.
