Potassium in the structure of Crystal Structure of Spin Labeled T4 Lysozyme Mutant K65V1/R76V1 (pdb 3k2r)

The binding sites of Potassium atom in the structure of Crystal Structure of Spin Labeled T4 Lysozyme Mutant K65V1/R76V1 (pdb code 3k2r). This binding sites where shown with 5.0 Angstroms radius around Potassium atom. The 3k2r structure was solved by D.TOLEDO WARSHAVIAK, D.CASCIO, V.V.KHRAMTSOV, W.L.HUBBELL, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 25.2-1.5 Space group P3221 a (A) 59.547 b (A) 59.547 c (A) 95.280 alpha (°) 90.00 beta (°) 90.00 gamma (°) 120.00 Rfactor (%) 19.7 Rfree (%) 21.2 Potassium Binding Sites: Potassium binding site 1 out of 1 in 3k2r Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Potassium in the PDB 3k2r.
