Strontium in the structure of Crystal Structure of Humnan Insulin Sr+2 Complex (pdb 3ilg)

The binding sites of Strontium atom in the structure of Crystal Structure of Humnan Insulin Sr+2 Complex (pdb code 3ilg). This binding sites where shown with 5.0 Angstroms radius around Strontium atom. The 3ilg structure was solved by N.RAGHAVENDRA, V.PATTABHI, S.S.RAJAN, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 16.9-1.9 Space group H3 a (A) 81.298 b (A) 81.298 c (A) 33.734 alpha (°) 90.00 beta (°) 90.00 gamma (°) 120.00 Rfactor (%) 19.2 Rfree (%) 27.8 Strontium Binding Sites: Strontium binding site 1 out of 2 in 3ilg Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Strontium in the PDB 3ilg.
