Copper in the structure of Crystal Structure of A Mutant Escherichia Coli Thioredoxin With An Arginine Insertion in the Active Site (pdb 1tho)

The binding sites of Copper atom in the structure of Crystal Structure of A Mutant Escherichia Coli Thioredoxin With An Arginine Insertion in the Active Site (pdb code 1tho). This binding sites where shown with 5.0 Angstroms radius around Copper atom. The 1tho structure was solved by M.NIKKOLA, K.LANGSETMO, J.A.FUCHS, H.EKLUND, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 2.3 Space group P61 a (A) 78.400 b (A) 78.400 c (A) 35.100 alpha (°) 90.00 beta (°) 90.00 gamma (°) 120.00 Rfactor (%) 17.3 Rfree (%) n/a Copper Binding Sites: Copper binding site 1 out of 1 in 1tho Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Copper in the PDB 1tho. 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: Asp43, conact list: Atom Atom Distance (A) Cu O A:Ser1 4.13 Cu N A:Ser1 2.60 Cu CB A:Ser1 4.52 Cu C A:Ser1 2.97 Cu CA A:Ser1 3.18 Cu N A:Asp2 2.09 Cu CB A:Asp2 3.09 Cu OD2 A:Asp2 3.87 Cu C A:Asp2 4.19 Cu OD1 A:Asp2 1.79 Cu CG A:Asp2 2.72 Cu CA A:Asp2 3.13 Cu N A:Lys3 4.10 Cu OD1 A:Asp43 4.39 Cu CG A:Asp43 4.77 interactive model:
