Gold in the structure of Transcriptional Regulatory Protein PF0864 From Pyrococcus Furiosus A Member of the Asnc Family (PF0864) (pdb 2ia0)

The binding sites of Gold atom in the structure of Transcriptional Regulatory Protein PF0864 From Pyrococcus Furiosus A Member of the Asnc Family (PF0864) (pdb code 2ia0). This binding sites where shown with 5.0 Angstroms radius around Gold atom. The 2ia0 structure was solved by H.YANG, J.CHANG, Z.J.LIU, J.P.ROSE, B.C.WANG, SOUTHEAST COLLABORATORY FORSTRUCTURAL GENOMICS, SOUTHEAST COLLABORATORY FOR STRUCTURAL GENOMICS(SECSG), with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 56.9-2.4 Space group P212121 a (A) 58.074 b (A) 70.372 c (A) 96.536 alpha (°) 90.00 beta (°) 90.00 gamma (°) 90.00 Rfactor (%) 20.5 Rfree (%) 26.9 Gold Binding Sites: Gold binding site 1 out of 2 in 2ia0 Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Gold in the PDB 2ia0.
