The binding sites of Zinc atom in the structure of Methionyl-Trna Synthetase From Thermus Thermophilus (pdb code 1a8h). This binding sites where shown with 5.0 Angstroms radius around Zinc atom. The 1a8h structure was solved by I.SUGIURA, O.NUREKI, Y.UGAJI, S.KUWABARA, B.LOBER, R.GIEGE, D.MORAS, S.YOKOYAMA, M.KONNO, RIKEN STRUCTURAL GENOMICS/PROTEOMICS INITIATIVE(RSGI), with X-Ray Crystallography technique, brief refinement statistics is given in the table below:
