Magnesium in the structure of Crystal Structure of An Apo Green Fluorescent Protein Zn Biosensor (pdb 1kyp)

The binding sites of Magnesium atom in the structure of Crystal Structure of An Apo Green Fluorescent Protein Zn Biosensor (pdb code 1kyp). This binding sites where shown with 5.0 Angstroms radius around Magnesium atom. The 1kyp structure was solved by D.P.BARONDEAU, C.J.KASSMANN, J.A.TAINER, E.D.GETZOFF, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 20.0-1.4 Space group P212121 a (A) 51.176 b (A) 62.355 c (A) 71.436 alpha (°) 90.00 beta (°) 90.00 gamma (°) 90.00 Rfactor (%) 15.2 Rfree (%) 21.9 Magnesium Binding Sites: Magnesium binding site 1 out of 1 in 1kyp Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Magnesium in the PDB 1kyp.
