Leucyl tRNA synthetase (LARS) is a 97 kDa, class IA aminoacyl-tRNA synthetase (ARS) that catalyzes the ligation of leucine with tRNA<sup>leu</sup> in an ATP dependent mechanism. LARS is a cytoplasmic enzyme that is found as part of the multisynthetase complex in mammals<ref>doi: 10.1007/978-3-319-46503-6_18</ref>. LARS has been shown to be involved with the mTOR pathways as a sensor of leucine levels within the cell<ref>doi: 10.1016/j.cell.2012.02.044</ref>.
