In enzymology a proline—tRNA ligase (EC 6.1.1.15) is an enzyme that catalyzes the chemical reactionATP + L-proline + tRNAPro AMP + diphosphate + L-prolyl-tRNAProThe 3 substrates of this enzyme are ATP L-proline and tRNA(Pro) whereas its 3 products are AMP diphosphate and L-prolyl-tRNA(Pro).This enzyme belongs to the family of ligases to be specific those forming carbon-oxygen bonds in aminoacyl-tRNA and related compounds.
