The binding sites of Vanadium atom in the structure of Crystal Structure of Guanosine-Free Ribonuclease T1, Complexed With Vanadate(V), Suggests Conformational Change Upon Substrate Binding (pdb code 3rnt). This binding sites where shown with 5.0 Angstroms radius around Vanadium atom. The 3rnt structure was solved by D.KOSTREWA, H.-W.CHOE, U.HEINEMANN, W.SAENGER, with X-Ray Crystallography technique, brief refinement statistics is given in the table below:
