Potassium in the structure of Structure of V8 Protease From Staphylococcus Aureus (pdb 2o8l)

The binding sites of Potassium atom in the structure of Structure of V8 Protease From Staphylococcus Aureus (pdb code 2o8l). This binding sites where shown with 5.0 Angstroms radius around Potassium atom. The 2o8l structure was solved by L.T.J.DELBAERE, L.PRASAD, Y.LEDUC, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 19.4-1.5 Space group P6522 a (A) 59.430 b (A) 59.430 c (A) 214.010 alpha (°) 90.00 beta (°) 90.00 gamma (°) 120.00 Rfactor (%) 18.8 Rfree (%) 21.9 Potassium Binding Sites: Potassium binding site 1 out of 1 in 2o8l Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Potassium in the PDB 2o8l. 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: Lys43, A: Pro101, A: Asn105, A: His107, A: Hoh1092, conact list: Atom Atom Distance (A) K CE A:Lys43 4.75 K NZ A:Lys43 4.81 K CB A:Pro101 4.95 K CG A:Pro101 4.91 K O A:Asn105 4.78 K NE2 A:His107 1.99 K ND1 A:His107 4.02 K CD2 A:His107 3.08 K CE1 A:His107 2.86 K CG A:His107 4.13 K O A:Hoh1092 4.10 interactive model:
