In enzymology an aspartate-tRNA ligase (EC 6.1.1.12) is an enzyme that catalyzes the chemical reactionATP + L-aspartate + tRNAAsp AMP + diphosphate + L-aspartyl-tRNAAspThe 3 substrates of this enzyme are ATP L-aspartate and tRNA(Asp) whereas its 3 products are AMP diphosphate and L-aspartyl-tRNA(Asp).This enzyme belongs to the family of ligases to be specific those forming carbon-oxygen bonds in aminoacyl-tRNA and related compounds.
