Isoleucyl-tRNA synthetase (IleRS) is a paradigm for understanding how specificity against smaller hydrophobic substrates evolved in both the synthetic and editing reactions. IleRS misactivates nonproteinogenic norvaline (Nva) and proteinogenic valine (Val), with a 200-fold lower efficiency than the cognate isoleucine
