Many mammalian mitochondrial aminoacyl-tRNA synthetases are of bacterial-type and share structural domains with homologous bacterial enzymes of the same specificity. Despite this high similarity, synthetases from bacteria are known for their inability to aminoacylate mitochondrial tRNAs, while mitoc

Aminoacyl-tRNA synthetases (aaRSs) ensure faithful translation of mRNA into protein by coupling an amino acid to a set of tRNAs with conserved anticodon sequences. Here, we show that in mitochondria of Saccharomyces cerevisiae, a single aaRS (MST1) recognizes and aminoacylates two natural tRNAs that
