Sodium in the structure of Crystal Structure of the Androgen Receptor Ligand Binding Domain in Complex With A Wxxvw Motif (pdb 1t76)

The binding sites of Sodium atom in the structure of Crystal Structure of the Androgen Receptor Ligand Binding Domain in Complex With A Wxxvw Motif (pdb code 1t76). This binding sites where shown with 5.0 Angstroms radius around Sodium atom. The 1t76 structure was solved by E.HUR, S.J.PFAFF, E.S.PAYNE, H.GRON, B.M.BUEHRER, R.J.FLETTERICK, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 20.0-2.1 Space group P212121 a (A) 53.386 b (A) 66.420 c (A) 70.606 alpha (°) 90.00 beta (°) 90.00 gamma (°) 90.00 Rfactor (%) 20.8 Rfree (%) 23.9 Sodium Binding Sites: Sodium binding site 1 out of 1 in 1t76 Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Sodium in the PDB 1t76. 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: Gln738, A: Glu897, A: Val901, A: Gln902, B: Trp101, A: Hoh51, conact list: Atom Atom Distance (A) Na NE2 A:Gln738 4.37 Na OE1 A:Gln738 3.69 Na CD A:Gln738 4.32 Na OE1 A:Glu897 4.23 Na OE2 A:Glu897 2.22 Na CD A:Glu897 3.23 Na CG A:Glu897 3.77 Na CB A:Val901 4.80 Na CG1 A:Val901 4.72 Na OE1 A:Gln902 3.82 Na CD A:Gln902 4.78 Na CG A:Gln902 4.96 Na CD1 B:Trp101 4.93 Na O A:Hoh51 3.13 interactive model:
