The binding sites of Zinc atom in the structure of Trna-Gunanine-Transglycosylase (Tgt) Mutant Y106F, C158V, A232S, V233G- Apo-Structure (pdb code 2nso). This binding sites where shown with 5.0 Angstroms radius around Zinc atom. The 2nso structure was solved by N.TIDTEN, A.HEINE, K.REUTER, G.KLEBE, with X-Ray Crystallography technique, brief refinement statistics is given in the table below:
