Glycine—tRNA ligase also known as glycyl-tRNA synthetase is an enzyme that in humans is encoded by the GARS gene.[3][4][5]
Function
This gene encodes glycyl-tRNA synthetase, one of the aminoacyl-tRNA synthetases that charge tRNAs with their cognate amino acids. The encoded enzyme is an (alpha)2 dimer which belongs to the class II family of tRNA synthetases.[5]

In enzymology, a glycine-tRNA ligase (EC 6.1.1.14) is an enzyme that catalyzes the chemical reaction
- ATP + glycine + tRNAGly AMP + diphosphate + glycyl-tRNAGly
The 3 substrates of this enzyme are ATP, glycine, and tRNA(Gly), whereas its 3 products are AMP, diphosphate, and glycyl-tRNA(Gly).
This enzyme belongs to the family of ligases, to be specific those forming carbon-oxygen bonds in aminoacyl-tRNA and related compounds. The systematic name of this enzyme class is glycine:tRNAGly ligase (AMP-forming). Other names in common use include glycyl-tRNA synthetase, glycyl-transfer ribonucleate synthetase, glycyl-transfer RNA synthetase, glycyl-transfer ribonucleic acid synthetase, and glycyl translase. This enzyme participates in glycine, serine and threonine metabolism and aminoacyl-trna biosynthesis.
Interactions
Glycyl-tRNA synthetase has been shown to interact with EEF1D.[6]
Clinical relevance
Glycyl-tRNA synthetase has been shown to be a target of autoantibodies in the human autoimmune diseases, polymyositis or dermatomyositis.[5]
The peripheral neuropathy Charcot-Marie-Tooth disease type 2D (CMT2D) has been liked to dominant mutations in GARS.[7] CMT2D usually manifests during the teenage years, and results in muscle weakness predominantly in the hands and feet.[8] Two mouse models of CMT2D have been used to better understand the disease, identifying that the disorder is caused by a toxic gain of function of the mutant glycine-tRNA ligase protein.[9] The CMT2D mice display peripheral nerve axon degeneration [10][11] and defective development of the neuromuscular junction.[12]
