Copper in the structure of Crystal Structure Analysis of A Mutant Escherichia Coli Thioredoxin in Which Lysine 36 Is Replaced By Glutamic Acid (pdb 2tir)

The binding sites of Copper atom in the structure of Crystal Structure Analysis of A Mutant Escherichia Coli Thioredoxin in Which Lysine 36 Is Replaced By Glutamic Acid (pdb code 2tir). This binding sites where shown with 5.0 Angstroms radius around Copper atom. The 2tir structure was solved by M.NIKKOLA, F.K.GLEASON, J.A.FUCHS, H.EKLUND, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 2.0 Space group P212121 a (A) 50.800 b (A) 26.800 c (A) 80.700 alpha (°) 90.00 beta (°) 90.00 gamma (°) 90.00 Rfactor (%) 19.9 Rfree (%) n/a Copper Binding Sites: Copper binding site 1 out of 1 in 2tir Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Copper in the PDB 2tir. Coordination sphere was calculated for all residues within 5.0 Angstroms distance from the central Copper atom, shown by VdW sphere Residues shown as a stick model or VDW spheres: A: Ser1, A: Asp2, A: Lys3, A: Hoh138, conact list: Atom Atom Distance (A) Cu O A:Ser1 3.95 Cu N A:Ser1 3.96 Cu CB A:Ser1 4.89 Cu C A:Ser1 3.43 Cu CA A:Ser1 4.15 Cu O A:Asp2 4.96 Cu N A:Asp2 2.86 Cu CB A:Asp2 2.47 Cu OD2 A:Asp2 2.27 Cu C A:Asp2 3.86 Cu OD1 A:Asp2 3.86 Cu CG A:Asp2 2.66 Cu CA A:Asp2 3.13 Cu N A:Lys3 3.77 Cu CB A:Lys3 4.94 Cu CE A:Lys3 4.53 Cu CD A:Lys3 4.55 Cu CG A:Lys3 4.06 Cu CA A:Lys3 4.99 Cu NZ A:Lys3 4.43 Cu O A:Hoh138 3.21 interactive model:
