Magnesium in the structure of D2 Domain of N-Ethylmaleimide-Sensitive Fusion Protein (pdb 1d2n)

The binding sites of Magnesium atom in the structure of D2 Domain of N-Ethylmaleimide-Sensitive Fusion Protein (pdb code 1d2n). This binding sites where shown with 5.0 Angstroms radius around Magnesium atom. The 1d2n structure was solved by C.U.LENZEN, D.STEINMANN, S.W.WHITEHEART, W.I.WEIS, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 50.0-1.8 Space group P6 a (A) 116.330 b (A) 116.330 c (A) 40.240 alpha (°) 90.00 beta (°) 90.00 gamma (°) 120.00 Rfactor (%) 19.9 Rfree (%) 22.3 Magnesium Binding Sites: Magnesium binding site 1 out of 1 in 1d2n Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Magnesium in the PDB 1d2n. Coordination sphere was calculated for all residues within 5.0 Angstroms distance from the central Magnesium atom, shown by VdW sphere Residues shown as a stick model or VDW spheres: A: Lys557, A: Thr558, A: Asp611, A: Asp612, A: Thr653, A: Anp1, A: Hoh160, A: Hoh242, A: Hoh243, A: Hoh244, A: Hoh347, conact list: Atom Atom Distance (A) Mg CB A:Lys557 4.98 Mg CE A:Lys557 4.89 Mg N A:Thr558 3.91 Mg CB A:Thr558 3.24 Mg CG2 A:Thr558 4.33 Mg OG1 A:Thr558 2.21 Mg CA A:Thr558 4.15 Mg OD2 A:Asp611 4.16 Mg OD1 A:Asp611 4.10 Mg CG A:Asp611 4.56 Mg OD2 A:Asp612 4.54 Mg CG A:Asp612 4.90 Mg OG1 A:Thr653 4.62 Mg PG A:Anp1 3.31 Mg O2G A:Anp1 2.12 Mg PA A:Anp1 4.56 Mg O2B A:Anp1 4.30 Mg O3A A:Anp1 4.27 Mg N3B A:Anp1 3.22 Mg O3G A:Anp1 4.26 Mg O2A A:Anp1 3.98 Mg O1B A:Anp1 2.15 Mg PB A:Anp1 3.21 Mg O1G A:Anp1 4.33 Mg O1A A:Anp1 4.89 Mg O A:Hoh160 3.98 Mg O A:Hoh242 2.24 Mg O A:Hoh243 2.32 Mg O A:Hoh244 2.31 Mg O A:Hoh347 4.34 interactive model:
