Sodium in the structure of X-Ray Structure of the Human Mitogen-Activated Protein Kinase Kinase 1 (MEK1) in A Binary Complex With K252A and MG2P (pdb 3eqf)

The binding sites of Sodium atom in the structure of X-Ray Structure of the Human Mitogen-Activated Protein Kinase Kinase 1 (MEK1) in A Binary Complex With K252A and MG2P (pdb code 3eqf). This binding sites where shown with 5.0 Angstroms radius around Sodium atom. The 3eqf structure was solved by T.O.FISCHMANN, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 50.0-2.7 Space group P6122 a (A) 78.160 b (A) 78.160 c (A) 222.990 alpha (°) 90.00 beta (°) 90.00 gamma (°) 120.00 Rfactor (%) n/a Rfree (%) n/a Sodium Binding Sites: Sodium binding site 1 out of 1 in 3eqf Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Sodium in the PDB 3eqf. 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: Asp65, A: Arg96, A: Glu138, A: Ca5, conact list: Atom Atom Distance (A) Na O A:Asp65 4.71 Na CB A:Asp65 4.38 Na OD2 A:Asp65 2.72 Na OD1 A:Asp65 2.35 Na CG A:Asp65 2.88 Na NH2 A:Arg96 4.78 Na NH1 A:Arg96 4.30 Na OE2 A:Glu138 4.79 Na CA A:Ca5 4.29 interactive model:
