Sodium in the structure of Phase Transition of Monoclinic Lysozyme Crystal Soaked in A Saturated Nacl Solution (pdb 2z19)

The binding sites of Sodium atom in the structure of Phase Transition of Monoclinic Lysozyme Crystal Soaked in A Saturated Nacl Solution (pdb code 2z19). This binding sites where shown with 5.0 Angstroms radius around Sodium atom. The 2z19 structure was solved by K.HARATA, T.AKIBA, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 25.0-1.1 Space group P1211 a (A) 26.085 b (A) 59.055 c (A) 30.703 alpha (°) 90.00 beta (°) 110.63 gamma (°) 90.00 Rfactor (%) 17.8 Rfree (%) 20.3 Sodium Binding Sites: Sodium binding site 1 out of 1 in 2z19 Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Sodium in the PDB 2z19. 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: Glu35, A: Asp52, A: Leu56, A: Gln57, A: Ile58, A: Asn59, A: Ala107, A: Trp108, A: Hoh140, A: Hoh141, A: Hoh142, A: Hoh156, A: Hoh161, A: Hoh175, conact list: Atom Atom Distance (A) Na OE2 A:Glu35 4.74 Na CB A:Asp52 4.06 Na CB A:Asp52 4.15 Na OD2 A:Asp52 2.76 Na OD2 A:Asp52 3.68 Na OD1 A:Asp52 3.86 Na OD1 A:Asp52 2.52 Na CG A:Asp52 3.29 Na CG A:Asp52 3.21 Na O A:Leu56 4.80 Na O A:Gln57 2.22 Na CB A:Gln57 4.15 Na C A:Gln57 3.45 Na CA A:Gln57 4.43 Na N A:Ile58 4.33 Na C A:Ile58 4.47 Na CA A:Ile58 4.39 Na N A:Asn59 4.19 Na CB A:Asn59 4.34 Na CA A:Asn59 4.66 Na O A:Ala107 4.35 Na CD1 A:Trp108 4.80 Na O A:Hoh140 2.34 Na O A:Hoh141 2.36 Na O A:Hoh142 2.23 Na O A:Hoh156 3.84 Na O A:Hoh161 4.08 Na O A:Hoh175 4.40 interactive model:
