Magnesium in the structure of Crystal Structure of G Alpha 12 in Complex With Gdp, MG2+ and ALF4- (pdb 1zca)

The binding sites of Magnesium atom in the structure of Crystal Structure of G Alpha 12 in Complex With Gdp, MG2+ and ALF4- (pdb code 1zca). This binding sites where shown with 5.0 Angstroms radius around Magnesium atom. The 1zca structure was solved by M.R.NANCE, J.J.G.TESMER, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 29.1-2.9 Space group P1211 a (A) 57.501 b (A) 85.230 c (A) 82.885 alpha (°) 90.00 beta (°) 106.09 gamma (°) 90.00 Rfactor (%) 23.6 Rfree (%) 29.6 Magnesium Binding Sites: Magnesium binding site 1 out of 2 in 1zca Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Magnesium in the PDB 1zca.
