Sodium in the structure of Crystal Structure of Atlantic Cod Trypsin Complexed With Benzamidine (pdb 2eek)

The binding sites of Sodium atom in the structure of Crystal Structure of Atlantic Cod Trypsin Complexed With Benzamidine (pdb code 2eek). This binding sites where shown with 5.0 Angstroms radius around Sodium atom. The 2eek structure was solved by D.IYAGUCHI, E.TOYOTA, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 20.0-1.9 Space group P212121 a (A) 47.213 b (A) 59.184 c (A) 63.736 alpha (°) 90.00 beta (°) 90.00 gamma (°) 90.00 Rfactor (%) 18.6 Rfree (%) 22.4 Sodium Binding Sites: Sodium binding site 1 out of 1 in 2eek Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Sodium in the PDB 2eek. Coordination sphere was calculated for all residues within 5.0 Angstroms distance from the central Sodium atom, shown by VdW sphere Residues shown as a stick model or VDW spheres: A: Tyr59, A: Val88, A: Ile89, A: Arg90, A: Hoh525, conact list: Atom Atom Distance (A) Na CE1 A:Tyr59 4.66 Na O A:Val88 4.53 Na CG2 A:Ile89 4.99 Na C A:Ile89 4.68 Na CA A:Ile89 4.58 Na O A:Arg90 4.62 Na N A:Arg90 3.76 Na CB A:Arg90 4.08 Na CD A:Arg90 4.56 Na CZ A:Arg90 4.11 Na CG A:Arg90 4.38 Na NE A:Arg90 3.54 Na NH2 A:Arg90 3.78 Na CA A:Arg90 4.49 Na O A:Hoh525 4.71 interactive model:
