In enzymology an alanine-tRNA ligase (EC 6.1.1.7) is an enzyme that catalyzes the chemical reactionATP + L-alanine + tRNAAla AMP + diphosphate + L-alanyl-tRNAAlaThe 3 substrates of this enzyme are ATP L-alanine and tRNA(Ala) whereas its 3 products are AMP diphosphate and L-alanyl-tRNA(Ala).This enzyme belongs to the family of ligases to be specific those forming carbon-oxygen bonds in aminoacyl-tRNA and related compounds.
