KARS (cytosolic lysyl tRNA synthetase) catalyzes the reaction of lysine, tRNA(Lys), and ATP to form Lys-tRNA(Lys), AMP, and pyrophosphate. The enzyme, a class II tRNA synthetase, is a homodimer found in the cell as a component of the mutienzyme aminoacyl-tRNA synthetase complex. The same gene encodes both cytosolic and mitochondrial KARS enzymes (Shiba et al. 1997).
