Sodium in the structure of Bacillus Licheniformis Alpha-Amylase (pdb 1bli)

The binding sites of Sodium atom in the structure of Bacillus Licheniformis Alpha-Amylase (pdb code 1bli). This binding sites where shown with 5.0 Angstroms radius around Sodium atom. The 1bli structure was solved by M.MACHIUS, N.DECLERCK, R.HUBER, G.WIEGAND, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 30.0-1.9 Space group P61 a (A) 91.300 b (A) 91.300 c (A) 137.700 alpha (°) 90.00 beta (°) 90.00 gamma (°) 120.00 Rfactor (%) 15.4 Rfree (%) 18.5 Sodium Binding Sites: Sodium binding site 1 out of 1 in 1bli Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Sodium in the PDB 1bli. Coordination sphere was calculated for all residues within 5.0 Angstroms distance from the central Sodium atom, shown by VdW sphere Residues shown as a stick model or VDW spheres: A: Asp161, A: Trp182, A: Asp183, A: Asp194, A: Asp200, A: Ile201, A: Asp202, A: Tyr203, A: Ca500, A: Ca600, A: Hoh1036, A: Hoh2080, conact list: Atom Atom Distance (A) Na N A:Asp161 4.94 Na CB A:Asp161 3.82 Na OD2 A:Asp161 2.44 Na OD1 A:Asp161 4.50 Na CG A:Asp161 3.44 Na CE3 A:Trp182 4.82 Na N A:Asp183 4.38 Na CB A:Asp183 4.17 Na OD2 A:Asp183 2.71 Na OD1 A:Asp183 3.74 Na CG A:Asp183 3.28 Na CA A:Asp183 4.94 Na CB A:Asp194 4.53 Na OD2 A:Asp194 2.47 Na OD1 A:Asp194 3.08 Na CG A:Asp194 3.10 Na O A:Asp200 4.33 Na CB A:Asp200 4.50 Na OD2 A:Asp200 2.43 Na C A:Asp200 4.45 Na OD1 A:Asp200 4.38 Na CG A:Asp200 3.60 Na O A:Ile201 2.50 Na N A:Ile201 4.55 Na C A:Ile201 3.49 Na CA A:Ile201 4.65 Na N A:Asp202 4.04 Na CB A:Asp202 4.91 Na C A:Asp202 4.64 Na CA A:Asp202 3.84 Na N A:Tyr203 4.31 Na CA A:Ca500 4.47 Na CA A:Ca600 4.12 Na O A:Hoh1036 3.85 Na O A:Hoh2080 3.61 interactive model:
