In enzymology a tryptophan-tRNA ligase (EC 6.1.1.2) is an enzyme that catalyzes the chemical reactionATP + L-tryptophan + tRNATrp AMP + diphosphate + L-tryptophyl-tRNATrpThe 3 substrates of this enzyme are ATP L-tryptophan and tRNA(Trp) whereas its 3 products are AMP diphosphate and L-tryptophyl-tRNATrp.This enzyme belongs to the family of ligases to be specific those forming carbon-oxygen bonds in aminoacyl-tRNA and related compounds.
