Magnesium in the structure of Crystal Structure Of Holo Form of Rat Catechol-O- Methyltransferase (pdb 2zth)

The binding sites of Magnesium atom in the structure of Crystal Structure Of Holo Form of Rat Catechol-O- Methyltransferase (pdb code 2zth). This binding sites where shown with 5.0 Angstroms radius around Magnesium atom. The 2zth structure was solved by E.TSUJI, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 39.9-2.6 Space group P212121 a (A) 32.903 b (A) 61.089 c (A) 105.369 alpha (°) 90.00 beta (°) 90.00 gamma (°) 90.00 Rfactor (%) 18.7 Rfree (%) 28.1 Magnesium Binding Sites: Magnesium binding site 1 out of 1 in 2zth Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Magnesium in the PDB 2zth. 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: Val42, A: Asp141, A: Asp169, A: Asn170, A: Sam305, A: Hoh383, conact list: Atom Atom Distance (A) Mg N A:Val42 4.48 Mg CB A:Val42 4.99 Mg CG2 A:Val42 3.76 Mg O A:Asp141 4.87 Mg CB A:Asp141 4.58 Mg OD2 A:Asp141 3.03 Mg OD1 A:Asp141 2.41 Mg CG A:Asp141 3.10 Mg CB A:Asp169 4.01 Mg OD2 A:Asp169 2.56 Mg OD1 A:Asp169 4.29 Mg CG A:Asp169 3.43 Mg CB A:Asn170 4.50 Mg ND2 A:Asn170 3.76 Mg OD1 A:Asn170 2.22 Mg CG A:Asn170 3.26 Mg CB A:Sam305 4.86 Mg CE A:Sam305 4.54 Mg O A:Hoh383 3.79 interactive model:
