Potassium in the structure of T13G Mutant Of the Atpase Fragment of Bovine HSC70 (pdb 2bup)

The binding sites of Potassium atom in the structure of T13G Mutant Of the Atpase Fragment of Bovine HSC70 (pdb code 2bup). This binding sites where shown with 5.0 Angstroms radius around Potassium atom. The 2bup structure was solved by M.C.SOUSA, D.B.MCKAY, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 30.0-1.7 Space group P212121 a (A) 143.350 b (A) 64.300 c (A) 46.230 alpha (°) 90.00 beta (°) 90.00 gamma (°) 90.00 Rfactor (%) 19.5 Rfree (%) 22.4 Potassium Binding Sites: Potassium binding site 1 out of 2 in 2bup Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Potassium in the PDB 2bup.
