GARS (mitochondrial glycyl tRNA synthetase) catalyzes the reaction of glycine, tRNA(Gly), and ATP to form Gly-tRNA(Gly), AMP, and pyrophosphate. The enzyme, a class II tRNA synthetase, is a dimer. Cytosolic and mitochondrial glycyl tRNA synthetase enzymes are both encoded by the same gene; the cytosolic protein lacks an aminoterminal 54-residue sequence found in the mitochondrial protein. Mutations in GARS are associated with Charcot-Marie-Tooth disease (Antonellis et al. 2007).
