In enzymology a tyrosine-tRNA ligase (EC 6.1.1.1) is an enzyme that catalyzes the chemical reactionATP + L-tyrosine + RNA AMP + diphosphate + L-tyrosyl-tRNATyrThe 3 substrates of this enzyme are ATP L-tyrosine and RNA whereas its 3 products are AMP diphosphate and L-tyrosyl-tRNA(Tyr).This enzyme belongs to the family of ligases to be specific those forming carbon-oxygen bonds in aminoacyl-tRNA and related compounds.
