Chromium in the structure of Crystal Structure of An Artificial Metalloprotein:Cr(III)(3, 3'-ME2-Salophen)/Apo-A71G Myoglobin (pdb 1j3f)

The binding sites of Chromium atom in the structure of Crystal Structure of An Artificial Metalloprotein:Cr(III)(3, 3'-ME2-Salophen)/Apo-A71G Myoglobin (pdb code 1j3f). This binding sites where shown with 5.0 Angstroms radius around Chromium atom. The 1j3f structure was solved by T.KOSHIYAMA, M.KONO, M.OHASHI, T.UENO, A.SUZUKI, T.YAMANE, Y.WATANABE, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 30.3-1.4 Space group P212121 a (A) 32.972 b (A) 58.787 c (A) 76.237 alpha (°) 90.00 beta (°) 90.00 gamma (°) 90.00 Rfactor (%) 19.4 Rfree (%) 21.9 Chromium Binding Sites: Chromium binding site 1 out of 1 in 1j3f Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Chromium in the PDB 1j3f. Coordination sphere was calculated for all residues within 5.0 Angstroms distance from the central Chromium atom, shown by VdW sphere Residues shown as a stick model or VDW spheres: A: His64, A: Val68, A: His93, A: Ile99, A: Czm180, A: Hoh203, conact list: Atom Atom Distance (A) Cr NE2 A:His64 4.21 Cr CE1 A:His64 4.67 Cr CG2 A:Val68 4.88 Cr NE2 A:His93 2.13 Cr ND1 A:His93 4.12 Cr CD2 A:His93 3.26 Cr CE1 A:His93 2.93 Cr CG A:His93 4.31 Cr CG2 A:Ile99 4.96 Cr CG1 A:Ile99 4.96 Cr CC3 A:Czm180 4.22 Cr CA2 A:Czm180 2.96 Cr CA3 A:Czm180 4.18 Cr CB A:Czm180 2.94 Cr CC6 A:Czm180 4.23 Cr OB A:Czm180 1.87 Cr CC1 A:Czm180 2.87 Cr NB A:Czm180 2.01 Cr CB1 A:Czm180 3.34 Cr CA A:Czm180 2.97 Cr NA A:Czm180 2.02 Cr CA7 A:Czm180 4.65 Cr CA6 A:Czm180 4.77 Cr CB6 A:Czm180 4.72 Cr CB2 A:Czm180 2.93 Cr CC2 A:Czm180 2.87 Cr OA A:Czm180 1.85 Cr CB3 A:Czm180 4.15 Cr CA1 A:Czm180 3.38 Cr CB7 A:Czm180 4.63 Cr O A:Hoh203 2.00 interactive model:
