Sodium in the structure of Sulfite Reductase Hemoprotein Nitrite Complex (pdb 3geo)

The binding sites of Sodium atom in the structure of Sulfite Reductase Hemoprotein Nitrite Complex (pdb code 3geo). This binding sites where shown with 5.0 Angstroms radius around Sodium atom. The 3geo structure was solved by B.R.CRANE, E.D.GETZOFF, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 10.0-2.1 Space group P212121 a (A) 69.800 b (A) 77.400 c (A) 87.800 alpha (°) 90.00 beta (°) 90.00 gamma (°) 90.00 Rfactor (%) 18.5 Rfree (%) n/a Sodium Binding Sites: Sodium binding site 1 out of 1 in 3geo Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Sodium in the PDB 3geo. 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: Phe361, A: Ile362, A: Glu363, A: Asn364, A: Gly365, A: Asn395, A: Gln396, A: Asn397, A: Hoh635, A: Hoh662, A: Hoh668, conact list: Atom Atom Distance (A) Na CD1 A:Phe361 4.40 Na CZ A:Phe361 4.98 Na CE1 A:Phe361 4.21 Na O A:Ile362 2.37 Na N A:Ile362 4.09 Na CB A:Ile362 4.71 Na C A:Ile362 3.45 Na CA A:Ile362 4.30 Na N A:Glu363 4.33 Na C A:Glu363 4.49 Na CA A:Glu363 4.40 Na N A:Asn364 4.05 Na C A:Asn364 4.67 Na CA A:Asn364 4.74 Na N A:Gly365 3.88 Na CA A:Gly365 4.44 Na O A:Asn395 2.89 Na C A:Asn395 3.98 Na O A:Gln396 3.07 Na N A:Gln396 4.45 Na OE1 A:Gln396 4.26 Na CB A:Gln396 3.58 Na C A:Gln396 3.43 Na CG A:Gln396 4.83 Na CA A:Gln396 3.98 Na N A:Asn397 4.06 Na CB A:Asn397 4.56 Na ND2 A:Asn397 3.86 Na OD1 A:Asn397 2.89 Na CG A:Asn397 3.52 Na CA A:Asn397 4.41 Na O A:Hoh635 3.97 Na O A:Hoh662 3.81 Na O A:Hoh668 3.69 interactive model:
