Magnesium in the structure of Structure of Espg-ARF6 Complex (pdb 3pcr)

The binding sites of Magnesium atom in the structure of Structure of Espg-ARF6 Complex (pdb code 3pcr). This binding sites where shown with 5.0 Angstroms radius around Magnesium atom. The 3pcr structure was solved by D.R.TOMCHICK, N.M.ALTO, A.S.SELYUNIN, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 29.0-2.5 Space group P43212 a (A) 104.566 b (A) 104.566 c (A) 98.238 alpha (°) 90.00 beta (°) 90.00 gamma (°) 90.00 Rfactor (%) 22.3 Rfree (%) 32.6 Magnesium Binding Sites: Magnesium binding site 1 out of 1 in 3pcr Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Magnesium in the PDB 3pcr. 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: B: Lys26, B: Thr27, B: Ile42, B: Thr44, B: Asp63, B: Gtp1230, B: Hoh192, B: Hoh193, B: Hoh197, conact list: Atom Atom Distance (A) Mg NZ B:Lys26 4.36 Mg N B:Thr27 4.10 Mg CB B:Thr27 3.24 Mg CG2 B:Thr27 4.22 Mg OG1 B:Thr27 2.09 Mg CA B:Thr27 4.23 Mg O B:Ile42 4.39 Mg N B:Thr44 3.88 Mg CB B:Thr44 3.03 Mg CG2 B:Thr44 4.07 Mg OG1 B:Thr44 2.16 Mg CA B:Thr44 4.08 Mg OD2 B:Asp63 3.65 Mg OD1 B:Asp63 4.37 Mg CG B:Asp63 4.43 Mg PG B:Gtp1230 2.66 Mg O3B B:Gtp1230 3.17 Mg O2G B:Gtp1230 1.96 Mg PA B:Gtp1230 4.35 Mg O2B B:Gtp1230 1.79 Mg O3A B:Gtp1230 4.00 Mg O3G B:Gtp1230 2.74 Mg O2A B:Gtp1230 3.89 Mg O1B B:Gtp1230 4.09 Mg PB B:Gtp1230 2.94 Mg O1G B:Gtp1230 4.05 Mg O1A B:Gtp1230 4.47 Mg O B:Hoh192 4.46 Mg O B:Hoh193 4.60 Mg O B:Hoh197 2.77 interactive model:
