Sodium in the structure of Complex of Recombinant Human Thrombin With A Inhibitor (pdb 2cf9)

The binding sites of Sodium atom in the structure of Complex of Recombinant Human Thrombin With A Inhibitor (pdb code 2cf9). This binding sites where shown with 5.0 Angstroms radius around Sodium atom. The 2cf9 structure was solved by E.SCHWEIZER, A.HOFFMANN-ROEDER, J.A.OLSEN, U.OBST-SANDER, B.WAGNER, M.KANSY, D.W.BANNER, F.DIEDERICH, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 71.8-1.8 Space group C121 a (A) 71.290 b (A) 71.840 c (A) 73.060 alpha (°) 90.00 beta (°) 100.56 gamma (°) 90.00 Rfactor (%) 16 Rfree (%) 19.8 Sodium Binding Sites: Sodium binding site 1 out of 1 in 2cf9 Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Sodium in the PDB 2cf9. 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: H: Tyr184A, H: Asp221, H: Arg221A, H: Asp222, H: Gly223, H: Lys224, H: Tyr225, H: Hoh2315, H: Hoh2316, H: Hoh2334, H: Hoh2335, H: Hoh2336, H: Hoh2360, H: Hoh2366, H: Hoh2370, H: Hoh2375, conact list: Atom Atom Distance (A) Na O H:Tyr184A 4.19 Na O H:Asp221 4.46 Na C H:Asp221 3.97 Na OD1 H:Asp221 4.53 Na CA H:Asp221 4.28 Na O H:Arg221A 2.25 Na N H:Arg221A 3.78 Na C H:Arg221A 3.29 Na CA H:Arg221A 4.15 Na N H:Asp222 4.16 Na C H:Asp222 4.58 Na CA H:Asp222 4.32 Na N H:Gly223 4.36 Na O H:Lys224 2.50 Na N H:Lys224 3.96 Na CB H:Lys224 4.58 Na C H:Lys224 3.58 Na CA H:Lys224 4.26 Na N H:Tyr225 4.58 Na CA H:Tyr225 4.84 Na O H:Hoh2315 2.92 Na O H:Hoh2316 2.68 Na O H:Hoh2334 3.91 Na O H:Hoh2335 4.35 Na O H:Hoh2336 4.38 Na O H:Hoh2360 4.87 Na O H:Hoh2366 2.39 Na O H:Hoh2370 4.07 Na O H:Hoh2375 2.16 interactive model:
