Potassium in the structure of Crystal Structure of Pyridoxal Kinase Complexed With Amp- Pcp and Pyridoxamine (pdb 1rft)

The binding sites of Potassium atom in the structure of Crystal Structure of Pyridoxal Kinase Complexed With Amp- Pcp and Pyridoxamine (pdb code 1rft). This binding sites where shown with 5.0 Angstroms radius around Potassium atom. The 1rft structure was solved by D.-C.LIANG, T.JIANG, M.-H.LI, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 20.0-2.8 Space group P3121 a (A) 103.687 b (A) 103.687 c (A) 58.604 alpha (°) 90.00 beta (°) 90.00 gamma (°) 120.00 Rfactor (%) 21.4 Rfree (%) 26.8 Potassium Binding Sites: Potassium binding site 1 out of 1 in 1rft Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Potassium in the PDB 1rft. Coordination sphere was calculated for all residues within 5.0 Angstroms distance from the central Potassium atom, shown by VdW sphere Residues shown as a stick model or VDW spheres: A: Asp113, A: Thr148, A: Pro149, A: Asn150, A: Glu153, A: Thr186, A: Zn403, A: Acp401, A: Hoh417, conact list: Atom Atom Distance (A) K OD2 A:Asp113 3.39 K OD1 A:Asp113 3.98 K CG A:Asp113 3.97 K O A:Thr148 2.36 K CB A:Thr148 4.15 K OG1 A:Thr148 3.79 K C A:Thr148 3.43 K CA A:Thr148 4.46 K O A:Pro149 4.18 K N A:Pro149 4.14 K C A:Pro149 3.93 K CA A:Pro149 4.06 K N A:Asn150 4.20 K ND2 A:Asn150 4.06 K CA A:Asn150 4.90 K OE1 A:Glu153 4.40 K CB A:Thr186 4.06 K CG2 A:Thr186 3.38 K OG1 A:Thr186 3.45 K ZN A:Zn403 4.16 K O3A A:Acp401 4.62 K O2A A:Acp401 4.94 K O1B A:Acp401 2.92 K PB A:Acp401 4.31 K O A:Hoh417 3.05 interactive model:
