Sodium in the structure of X-Ray Structure of the Cytochrome-C(2)-Photosynthetic Reaction Center Electron Transfer Complex From Rhodobacter Sphaeroides in Type II Co- Crystals (pdb 1l9b)

The binding sites of Sodium atom in the structure of X-Ray Structure of the Cytochrome-C(2)-Photosynthetic Reaction Center Electron Transfer Complex From Rhodobacter Sphaeroides in Type II Co- Crystals (pdb code 1l9b). This binding sites where shown with 5.0 Angstroms radius around Sodium atom. The 1l9b structure was solved by H.L.AXELROD, E.C.ABRESCH, M.Y.OKAMURA, A.P.YEH, D.C.REES, G.FEHER, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 45.7-2.4 Space group P1211 a (A) 78.222 b (A) 115.650 c (A) 79.677 alpha (°) 90.00 beta (°) 110.29 gamma (°) 90.00 Rfactor (%) 22 Rfree (%) 26.4 Sodium Binding Sites: Sodium binding site 1 out of 1 in 1l9b Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Sodium in the PDB 1l9b. 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: L: Trp266, M: Leu86, M: Phe90, M: Hoh1022, conact list: Atom Atom Distance (A) Na CD1 L:Trp266 3.94 Na CD2 L:Trp266 3.87 Na CE3 L:Trp266 4.55 Na CG L:Trp266 4.20 Na CZ3 L:Trp266 4.73 Na CZ2 L:Trp266 3.65 Na CE2 L:Trp266 3.37 Na NE1 L:Trp266 3.42 Na CH2 L:Trp266 4.33 Na O M:Leu86 4.73 Na CB M:Phe90 4.96 Na CE2 M:Phe90 3.21 Na CD1 M:Phe90 4.37 Na CD2 M:Phe90 3.44 Na CZ M:Phe90 3.64 Na CE1 M:Phe90 4.20 Na CG M:Phe90 4.04 Na O M:Hoh1022 4.14 interactive model:
