Magnesium in the structure of Structure of Btb/Poz Transcription Repression Domain From Promelocytic Leukemia Zinc Finger Oncoprotein (pdb 1cs3)

The binding sites of Magnesium atom in the structure of Structure of Btb/Poz Transcription Repression Domain From Promelocytic Leukemia Zinc Finger Oncoprotein (pdb code 1cs3). This binding sites where shown with 5.0 Angstroms radius around Magnesium atom. The 1cs3 structure was solved by X.LI, F.J.RAUSCHER 3RD, R.MARMORSTEIN, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 20.0-2.0 Space group I222 a (A) 38.800 b (A) 78.200 c (A) 85.200 alpha (°) 90.00 beta (°) 90.00 gamma (°) 90.00 Rfactor (%) 22.8 Rfree (%) 27.2 Magnesium Binding Sites: Magnesium binding site 1 out of 1 in 1cs3 Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Magnesium in the PDB 1cs3. 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: Asp41, A: Leu72, A: Asp73, A: Leu75, A: Gol1529, A: Hoh1005, A: Hoh1015, A: Hoh1017, A: Hoh1024, A: Hoh1025, A: Hoh1059, conact list: Atom Atom Distance (A) Mg N A:Asp41 4.82 Mg CB A:Asp41 4.54 Mg OD2 A:Asp41 3.51 Mg OD1 A:Asp41 2.23 Mg CG A:Asp41 3.20 Mg CA A:Asp41 4.78 Mg O A:Leu72 4.73 Mg O A:Asp73 4.17 Mg C A:Asp73 4.59 Mg CA A:Asp73 4.55 Mg O A:Leu75 4.09 Mg C A:Leu75 4.91 Mg C1 A:Gol1529 4.43 Mg O1 A:Gol1529 3.68 Mg O A:Hoh1005 2.46 Mg O A:Hoh1015 4.17 Mg O A:Hoh1017 2.20 Mg O A:Hoh1024 2.28 Mg O A:Hoh1025 2.13 Mg O A:Hoh1059 4.18 interactive model:
