Nickel in the structure of Rat Anionic N143H, E151H Trypsin Complexed to A86H Ecotin; Nickel- Bound (pdb 1slw)

The binding sites of Nickel atom in the structure of Rat Anionic N143H, E151H Trypsin Complexed to A86H Ecotin; Nickel- Bound (pdb code 1slw). This binding sites where shown with 5.0 Angstroms radius around Nickel atom. The 1slw structure was solved by L.S.BRINEN, R.J.FLETTERICK, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 6.0-2.0 Space group C121 a (A) 86.380 b (A) 56.230 c (A) 81.230 alpha (°) 90.00 beta (°) 92.81 gamma (°) 90.00 Rfactor (%) 17.9 Rfree (%) 25.3 Nickel Binding Sites: Nickel binding site 1 out of 1 in 1slw Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Nickel in the PDB 1slw. Coordination sphere was calculated for all residues within 5.0 Angstroms distance from the central Nickel atom, shown by VdW sphere Residues shown as a stick model or VDW spheres: A: His86, B: His143, B: His151, A: Hoh143, B: Hoh253, conact list: Atom Atom Distance (A) Ni NE2 A:His86 2.15 Ni ND1 A:His86 4.22 Ni CD2 A:His86 3.28 Ni CE1 A:His86 3.01 Ni CG A:His86 4.36 Ni NE2 B:His143 2.61 Ni ND1 B:His143 4.54 Ni CD2 B:His143 3.64 Ni CE1 B:His143 3.39 Ni CG B:His143 4.68 Ni NE2 B:His151 2.24 Ni ND1 B:His151 4.30 Ni CD2 B:His151 3.37 Ni CE1 B:His151 3.09 Ni CG B:His151 4.45 Ni O A:Hoh143 4.83 Ni O B:Hoh253 2.50 interactive model:
