Sodium in the structure of X-Ray Structure of the Human Mitogen-Activated Protein Kinase Kinase 1 (MEK1) in A Ternary Complex With Pd, Adp and MG2P (pdb 3eqg)

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 Ternary Complex With Pd, Adp and MG2P (pdb code 3eqg). This binding sites where shown with 5.0 Angstroms radius around Sodium atom. The 3eqg structure was solved by T.O.FISCHMANN, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 16.5-2.5 Space group P6122 a (A) 76.000 b (A) 76.000 c (A) 222.320 alpha (°) 90.00 beta (°) 90.00 gamma (°) 120.00 Rfactor (%) 20.7 Rfree (%) 27.3 Sodium Binding Sites: Sodium binding site 1 out of 1 in 3eqg Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Sodium in the PDB 3eqg. 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: Ser135, A: Asp136, A: Glu138, A: Ca5, conact list: Atom Atom Distance (A) Na CB A:Asp65 4.12 Na OD2 A:Asp65 2.22 Na OD1 A:Asp65 2.38 Na CG A:Asp65 2.60 Na NH2 A:Arg96 4.37 Na OG A:Ser135 4.71 Na CB A:Asp136 4.96 Na OD2 A:Asp136 4.52 Na OD1 A:Asp136 2.71 Na CG A:Asp136 3.90 Na OE2 A:Glu138 4.73 Na CA A:Ca5 4.13 interactive model:
