Potassium in the structure of Human SUN2-KASH2 Complex (pdb 4dxs)

The binding sites of Potassium atom in the structure of Human SUN2-KASH2 Complex (pdb code 4dxs). This binding sites where shown with 5.0 Angstroms radius around Potassium atom. The 4dxs structure was solved by B.SOSA, T.U.SCHWARTZ, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 36.1-2.7 Space group H32 a (A) 79.320 b (A) 79.320 c (A) 260.030 alpha (°) 90.00 beta (°) 90.00 gamma (°) 120.00 Rfactor (%) 18.2 Rfree (%) 24.1 Potassium Binding Sites: Potassium binding site 1 out of 1 in 4dxs Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Potassium in the PDB 4dxs. Coordination sphere was calculated for all residues within 5.0 Angstroms distance from the central Potassium atom, shown by VdW sphere Residues shown as a stick model or VDW spheres: A: Val590, A: Ile591, A: Gln593, A: Pro594, A: Asp595, A: Val596, A: Asn600, A: Tyr707, A: Arg708, conact list: Atom Atom Distance (A) K O A:Val590 2.74 K CB A:Val590 4.03 K CG2 A:Val590 4.51 K C A:Val590 3.70 K CA A:Val590 4.35 K O A:Ile591 4.77 K N A:Ile591 4.60 K C A:Ile591 4.76 K CA A:Ile591 4.60 K O A:Gln593 2.95 K N A:Gln593 4.40 K CB A:Gln593 4.39 K C A:Gln593 3.85 K CA A:Gln593 4.45 K N A:Pro594 4.80 K C A:Pro594 4.68 K CA A:Pro594 4.99 K O A:Asp595 3.29 K N A:Asp595 4.51 K C A:Asp595 4.20 K CA A:Asp595 4.95 K N A:Val596 4.94 K CG1 A:Val596 4.22 K CA A:Val596 4.88 K O A:Asn600 3.50 K C A:Asn600 4.71 K O A:Tyr707 2.71 K C A:Tyr707 3.62 K CA A:Tyr707 4.43 K N A:Arg708 4.39 K CB A:Arg708 4.41 K CA A:Arg708 4.54 interactive model:
