Potassium in the structure of Polar and Non-Polar Cavities in Phage T4 Lysozyme (pdb 3dke)

The binding sites of Potassium atom in the structure of Polar and Non-Polar Cavities in Phage T4 Lysozyme (pdb code 3dke). This binding sites where shown with 5.0 Angstroms radius around Potassium atom. The 3dke structure was solved by L.J.LIU, B.W.MATTHEWS, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 52.1-1.2 Space group P3221 a (A) 60.226 b (A) 60.226 c (A) 96.677 alpha (°) 90.00 beta (°) 90.00 gamma (°) 120.00 Rfactor (%) 15.5 Rfree (%) 17.3 Potassium Binding Sites: Potassium binding site 1 out of 1 in 3dke Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Potassium in the PDB 3dke. 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: X: Asp10, X: Glu11, X: Gly12, X: Tyr18, X: Gly30, X: Hoh906, X: Hoh937, X: Hoh947, X: Hoh956, X: Hoh1028, X: Hoh1045, X: Hoh1102, X: Hoh1103, conact list: Atom Atom Distance (A) K O X:Asp10 4.84 K O X:Glu11 2.87 K OE1 X:Glu11 3.04 K CB X:Glu11 4.36 K CD X:Glu11 4.22 K C X:Glu11 3.74 K CG X:Glu11 4.92 K CA X:Glu11 3.90 K N X:Gly12 4.98 K CE2 X:Tyr18 4.18 K CZ X:Tyr18 3.91 K OH X:Tyr18 2.76 K N X:Gly30 4.84 K CA X:Gly30 4.60 K O X:Hoh906 2.83 K O X:Hoh937 3.78 K O X:Hoh947 2.72 K O X:Hoh956 2.75 K O X:Hoh1028 3.48 K O X:Hoh1045 2.88 K O X:Hoh1102 4.85 K O X:Hoh1103 3.72 interactive model:
