<abstract><p>Aminoacyl-tRNA synthetases (aaRSs) are a group of ancient enzymes catalyzing aminoacylation and editing reactions for protein biosynthesis. Increasing evidence suggests that these critical enzymes are often associated with mammalian disorders. Therefore, complete determination of the enzymes functions is essential for informed diagnosis and treatment. Here, we show that a yeast knock-out strain for the threonyl-tRNA synthetase (ThrRS) gene is an excellent platform for such an investigation. <italic>Saccharomyces cerevisiae</italic>
ThrRS has a unique modular structure containing four structural domains and a eukaryote-specific N-terminal extension. Using randomly mutated libraries of the ThrRS gene (<italic>thrS</italic>
) and a genetic screen, a set of loss-of-function mutants were identified. The mutations affected the synthetic and editing activities and influenced the dimer interface. The results also highlighted the role of the N-terminal extension for enzymatic activity and protein stability. To gain insights into the pathological mechanisms induced by mutated aaRSs, we systematically introduced the loss-of-function mutations into the human cytoplasmic ThrRS gene. All mutations induced similar detrimental effects, showing that the yeast model could be used to study pathology-associated point mutations in mammalian aaRSs.</p>
