  • Backbone $^1H$, $^{13}C$ and $^{15}N$ resonance assignments are presented for the anticodon binding domain (residues 557-674) of human glycyl-tRNA synthetase (GRS). Role of the anticodon binding domain (ABD) of GRS as an anticancer ligand has recently been reported and its role in other diseases like Charcot-Marie-Tooth (CMT) and polymyositis have increased its interest. NMR assignments were completed using the isotope [$^{13}C/^{15}N$]-enriched protein and chemical shifts based secondary structure analysis with TALOS+ demonstrate similar secondary structure as reported in X-ray structure PDB 2ZT8, except some C-terminal residues. NMR signals from the N-terminal residues 557 to 571 and 590 to 614 showed very weak or no signals exhibiting dynamics or conformational exchange in NMR timescale.
