General Description

spinqualitylabelsall models LARS (E coli) ternary complex with tRNAleu and leucyl adenylate analogue Show:Asymmetric Unit Biological Assembly Drag the structure with the mouse to rotate   Export Animated Image Leucyl tRNA synthetase (LARS) is a 97 kDa, class IA aminoacyl-tRNA synthetase (ARS) that catalyzes the ligation of leucine with tRNAleu in an ATP dependent mechanism. LARS is a cytoplasmic enzyme that is found as part of the multisynthetase complex in mammals[1]. LARS has been shown to be involved with the mTOR pathways as a sensor of leucine levels within the cell[2]. Mutations in LARS2, the mitochondrial version of the enzyme, have been linked to Perrault syndrome characterized by premature ovarian failure in females and progressive hearing loss in both sexes[3] Structure Catalytic Domain [4] [5]
