Aluminium in the structure of Structures Of Active Conformations Of Gi Alpha 1 and the Mechanism of Gtp Hydrolysis (pdb 1gfi)

The binding sites of Aluminium atom in the structure of Structures Of Active Conformations Of Gi Alpha 1 and the Mechanism of Gtp Hydrolysis (pdb code 1gfi). This binding sites where shown with 5.0 Angstroms radius around Aluminium atom. The 1gfi structure was solved by D.E.COLEMAN, A.M.BERGHUIS, S.R.SPRANG, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 8.0-2.2 Space group P3221 a (A) 80.500 b (A) 80.500 c (A) 106.550 alpha (°) 90.00 beta (°) 90.00 gamma (°) 120.00 Rfactor (%) 21.4 Rfree (%) 28.4 Aluminium Binding Sites: Aluminium binding site 1 out of 1 in 1gfi Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Aluminium in the PDB 1gfi. Coordination sphere was calculated for all residues within 5.0 Angstroms distance from the central Aluminium atom, shown by VdW sphere Residues shown as a stick model or VDW spheres: A: Gly42, A: Glu43, A: Lys46, A: Arg178, A: Thr181, A: Val201, A: Gly202, A: Gly203, A: Gln204, A: Mg356, A: Alf357, A: Gdp355, A: Hoh401, A: Hoh410, A: Hoh412, conact list: Atom Atom Distance (A) Al C A:Gly42 4.47 Al CA A:Gly42 4.14 Al N A:Glu43 3.74 Al CA A:Glu43 4.63 Al CE A:Lys46 4.61 Al NZ A:Lys46 4.08 Al CZ A:Arg178 4.38 Al NH2 A:Arg178 3.92 Al NH1 A:Arg178 3.84 Al O A:Thr181 4.65 Al N A:Thr181 4.37 Al CB A:Thr181 4.48 Al OG1 A:Thr181 4.47 Al CA A:Thr181 4.96 Al O A:Val201 4.93 Al C A:Gly202 4.87 Al CA A:Gly202 4.57 Al N A:Gly203 4.09 Al CA A:Gly203 4.97 Al NE2 A:Gln204 4.14 Al OE1 A:Gln204 4.10 Al CD A:Gln204 4.53 Al MG A:Mg356 3.57 Al F4 A:Alf357 1.77 Al F3 A:Alf357 1.81 Al F2 A:Alf357 1.85 Al AL A:Alf357 0.00 Al F1 A:Alf357 1.81 Al O3B A:Gdp355 1.95 Al O1B A:Gdp355 3.70 Al PB A:Gdp355 3.02 Al O2B A:Gdp355 3.61 Al O3A A:Gdp355 4.26 Al O A:Hoh401 2.18 Al O A:Hoh410 4.35 Al O A:Hoh412 4.04 interactive model:
