Nickel in the structure of Escherichia Coli Ferric Hydroxamate Uptake Receptor (Fhua) in Complex Delta Two-Albomycin (pdb 1qkc)

The binding sites of Nickel atom in the structure of Escherichia Coli Ferric Hydroxamate Uptake Receptor (Fhua) in Complex Delta Two-Albomycin (pdb code 1qkc). This binding sites where shown with 5.0 Angstroms radius around Nickel atom. The 1qkc structure was solved by A.D.FERGUSON, V.BRAUN, H.-P.FIEDLER, J.W.COULTON, K.DIEDERICHS, W.WELTE, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 50.0-3.1 Space group P61 a (A) 171.800 b (A) 171.800 c (A) 86.350 alpha (°) 90.00 beta (°) 90.00 gamma (°) 120.00 Rfactor (%) 22.2 Rfree (%) 28.3 Nickel Binding Sites: Nickel binding site 1 out of 1 in 1qkc Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Nickel in the PDB 1qkc. 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: Gmh1011, A: Po41016, A: Glc1017, A: Gla1019, conact list: Atom Atom Distance (A) Ni C4 A:Gmh1011 4.73 Ni C3 A:Gmh1011 4.25 Ni O3 A:Gmh1011 4.87 Ni O4 A:Gmh1011 4.40 Ni O1 A:Po41016 4.31 Ni O2 A:Po41016 4.81 Ni P A:Po41016 3.76 Ni O3 A:Po41016 2.34 Ni C6 A:Glc1017 4.19 Ni O5 A:Glc1017 3.50 Ni C5 A:Glc1017 4.47 Ni C1 A:Glc1017 4.32 Ni O6 A:Glc1017 3.70 Ni O2 A:Gla1019 3.96 Ni C1 A:Gla1019 4.53 Ni C2 A:Gla1019 4.91 interactive model:
