Potassium in the structure of Structure of A F112H Variant Pduo-Type Atp:Corrinoid Adenosyltransferase From Lactobacillus Reuteri Complexed With Cobalamin and Atp (pdb 3gah)

The binding sites of Potassium atom in the structure of Structure of A F112H Variant Pduo-Type Atp:Corrinoid Adenosyltransferase From Lactobacillus Reuteri Complexed With Cobalamin and Atp (pdb code 3gah). This binding sites where shown with 5.0 Angstroms radius around Potassium atom. The 3gah structure was solved by M.ST MAURICE, P.E.MERA, J.C.ESCALANTE-SEMERENA, I.RAYMENT, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 30.0-1.2 Space group H3 a (A) 80.814 b (A) 80.814 c (A) 89.492 alpha (°) 90.00 beta (°) 90.00 gamma (°) 120.00 Rfactor (%) 16 Rfree (%) 18.2 Potassium Binding Sites: Potassium binding site 1 out of 1 in 3gah Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Potassium in the PDB 3gah. 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: Ile3, A: Tyr4, A: Thr5, A: Atp999, A: B12800, A: Mg189, A: Hoh193, A: Hoh194, conact list: Atom Atom Distance (A) K O A:Ile3 2.61 K CB A:Ile3 4.91 K C A:Ile3 3.68 K CA A:Ile3 4.80 K N A:Tyr4 4.27 K CB A:Tyr4 4.89 K C A:Tyr4 4.76 K CA A:Tyr4 3.99 K N A:Thr5 4.45 K PG A:Atp999 3.33 K O3B A:Atp999 4.03 K O2G A:Atp999 2.78 K PA A:Atp999 3.49 K O5' A:Atp999 4.86 K O3A A:Atp999 4.40 K O3G A:Atp999 4.71 K O2A A:Atp999 2.74 K PB A:Atp999 4.79 K O1G A:Atp999 2.84 K O1A A:Atp999 3.42 K O28 A:B12800 4.07 K O28 A:B12800 3.92 K C35 A:B12800 3.53 K C35 A:B12800 3.57 K C37 A:B12800 4.56 K C37 A:B12800 4.62 K C5 A:B12800 4.51 K C5 A:B12800 4.61 K N40 A:B12800 4.81 K MG A:Mg189 4.01 K O A:Hoh193 3.83 K O A:Hoh194 4.04 interactive model:
