Magnesium in the structure of Refinement of Placental Alkaline Phosphatase Complexed With Nitrophenyl (pdb 3mk1)

The binding sites of Magnesium atom in the structure of Refinement of Placental Alkaline Phosphatase Complexed With Nitrophenyl (pdb code 3mk1). This binding sites where shown with 5.0 Angstroms radius around Magnesium atom. The 3mk1 structure was solved by B.STEC, A.CHELTSOV, J.L.MILLAN, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 70.0-1.6 Space group C2221 a (A) 88.346 b (A) 114.573 c (A) 106.568 alpha (°) 90.00 beta (°) 90.00 gamma (°) 90.00 Rfactor (%) 13.9 Rfree (%) 17.8 Magnesium Binding Sites: Magnesium binding site 1 out of 1 in 3mk1 Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Magnesium in the PDB 3mk1.
