Aminoacyl-tRNA synthetases (ARSs) are known as essential enzymes linking amino acids to tRNAs in the initial stage of protein synthesis. As living organisms get higher degree of complexity, they have acquired additional domains to coordinate protein synthesis with system development. This lecture introduces how these enzymes have evolved to control system development of higher order organisms and how they can be used as a rich source for future medicine that is signified by 4Ps (precision, preventive, predictive and participatory). Functional changes of human ARSs appear to be finely controlled by metamorphosis through proteolysis, splicing and post-translational modifications. Disease-specific mutations, expression and interactions of these enzymes are actively explored to develop new therapeutics and biomarkers.
