Iridium in the structure of Bacteriophage T4 Gene 59 Helicase Assembly Protein (pdb 1c1k)

The binding sites of Iridium atom in the structure of Bacteriophage T4 Gene 59 Helicase Assembly Protein (pdb code 1c1k). This binding sites where shown with 5.0 Angstroms radius around Iridium atom. The 1c1k structure was solved by T.C.MUESER, C.E.JONES, N.G.NOSSAL, C.C.HYDE, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 5.0-1.4 Space group P212121 a (A) 31.865 b (A) 65.882 c (A) 108.166 alpha (°) 90.00 beta (°) 90.00 gamma (°) 90.00 Rfactor (%) 20 Rfree (%) 25.3 Iridium Binding Sites: Iridium binding site 1 out of 2 in 1c1k Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Iridium in the PDB 1c1k.
