In enzymology a cysteine-tRNA ligase (EC 6.1.1.16) is an enzyme that catalyzes the chemical reactionATP + L-cysteine + tRNACys AMP + diphosphate + L-cysteinyl-tRNACysThe 3 substrates of this enzyme are ATP L-cysteine and tRNA(Cys) whereas its 3 products are AMP diphosphate and L-cysteinyl-tRNA(Cys).This enzyme belongs to the family of ligases to be specific those forming carbon-oxygen bonds in aminoacyl-tRNA and related compounds.
