Magnesium in the structure of X-Ray Structures Of The Mgadp, Mgatpgammas, and Mgamppnp Complexes of the Dictyostelium Discoideum Myosin Motor Domain (pdb 1mma)

The binding sites of Magnesium atom in the structure of X-Ray Structures Of The Mgadp, Mgatpgammas, and Mgamppnp Complexes of the Dictyostelium Discoideum Myosin Motor Domain (pdb code 1mma). This binding sites where shown with 5.0 Angstroms radius around Magnesium atom. The 1mma structure was solved by A.M.GULICK, C.B.BAUER, J.B.THODEN, I.RAYMENT, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 20.0-2.1 Space group P21212 a (A) 103.600 b (A) 179.000 c (A) 53.900 alpha (°) 90.00 beta (°) 90.00 gamma (°) 90.00 Rfactor (%) 21.9 Rfree (%) n/a Magnesium Binding Sites: Magnesium binding site 1 out of 1 in 1mma Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Magnesium in the PDB 1mma. 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: Lys185, A: Thr186, A: Asn233, A: Ser236, A: Ser237, A: Asp454, A: Adp999, A: Hoh8023, A: Hoh8142, A: Hoh8158, A: Hoh8202, A: Hoh9951, A: Hoh9953, A: Hoh9954, A: Hoh9955, conact list: Atom Atom Distance (A) Mg CB A:Lys185 4.62 Mg CE A:Lys185 4.69 Mg C A:Lys185 4.89 Mg N A:Thr186 3.87 Mg CB A:Thr186 3.09 Mg CG2 A:Thr186 4.07 Mg OG1 A:Thr186 2.13 Mg CA A:Thr186 4.07 Mg ND2 A:Asn233 4.98 Mg C A:Ser236 4.97 Mg N A:Ser237 3.86 Mg CB A:Ser237 3.17 Mg OG A:Ser237 2.07 Mg CA A:Ser237 4.11 Mg OD2 A:Asp454 4.15 Mg OD1 A:Asp454 4.12 Mg CG A:Asp454 4.57 Mg O3B A:Adp999 3.49 Mg PA A:Adp999 4.82 Mg O2A A:Adp999 4.26 Mg O1B A:Adp999 4.25 Mg PB A:Adp999 3.27 Mg O2B A:Adp999 1.96 Mg O3A A:Adp999 4.36 Mg O A:Hoh8023 4.69 Mg O A:Hoh8142 4.95 Mg O A:Hoh8158 4.13 Mg O A:Hoh8202 4.35 Mg O A:Hoh9951 2.25 Mg O A:Hoh9953 2.11 Mg O A:Hoh9954 2.24 Mg O A:Hoh9955 4.88 interactive model:
