Sodium in the structure of Two Chain Form of the 66.3 Kda Protein At 1.8 Angstroem (pdb 3fgr)

The binding sites of Sodium atom in the structure of Two Chain Form of the 66.3 Kda Protein At 1.8 Angstroem (pdb code 3fgr). This binding sites where shown with 5.0 Angstroms radius around Sodium atom. The 3fgr structure was solved by K.LAKOMEK, A.DICKMANNS, R.FICNER, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 29.3-1.8 Space group C121 a (A) 148.737 b (A) 89.560 c (A) 64.811 alpha (°) 90.00 beta (°) 98.69 gamma (°) 90.00 Rfactor (%) 15.2 Rfree (%) 18.2 Sodium Binding Sites: Sodium binding site 1 out of 1 in 3fgr Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Sodium in the PDB 3fgr. 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: Ser246, B: Ocs249, B: Gly314, B: Asp315, B: Asp316, B: Glu328, B: Thr329, B: Thr330, B: Tyr379, B: Asn381, conact list: Atom Atom Distance (A) Na CB A:Ser246 3.91 Na OG A:Ser246 3.14 Na C A:Ser246 4.93 Na CB B:Ocs249 4.68 Na SG B:Ocs249 3.37 Na OD2 B:Ocs249 2.76 Na OD3 B:Ocs249 4.35 Na OD1 B:Ocs249 3.00 Na O B:Gly314 3.97 Na O B:Asp315 2.86 Na C B:Asp315 3.73 Na CA B:Asp315 4.78 Na N B:Asp316 4.28 Na OD1 B:Asp316 4.87 Na O B:Glu328 4.38 Na OE1 B:Glu328 2.76 Na OE2 B:Glu328 3.03 Na CD B:Glu328 3.25 Na C B:Glu328 4.99 Na CG B:Glu328 4.74 Na C B:Thr329 4.69 Na CA B:Thr329 4.64 Na N B:Thr330 4.10 Na CB B:Thr330 4.05 Na OG1 B:Thr330 2.82 Na CA B:Thr330 4.63 Na CE2 B:Tyr379 4.05 Na CZ B:Tyr379 3.74 Na CE1 B:Tyr379 4.81 Na OH B:Tyr379 2.84 Na OD1 B:Asn381 4.65 interactive model:
