Cadmium in the structure of Crystal Structure of the Single-Stranded Dna-Binding Protein From Mycobacterium Smegmatis (pdb 1x3e)

The binding sites of Cadmium atom in the structure of Crystal Structure of the Single-Stranded Dna-Binding Protein From Mycobacterium Smegmatis (pdb code 1x3e). This binding sites where shown with 5.0 Angstroms radius around Cadmium atom. The 1x3e structure was solved by K.SAIKRISHNAN, G.P.MANJUNATH, P.SINGH, J.JEYAKANTHAN, Z.DAUTER, K.SEKAR, K.MUNIYAPPA, M.VIJAYAN, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 30.0-2.1 Space group P3121 a (A) 78.620 b (A) 78.620 c (A) 79.834 alpha (°) 90.00 beta (°) 90.00 gamma (°) 120.00 Rfactor (%) 20 Rfree (%) 23.9 Cadmium Binding Sites: Cadmium binding site 1 out of 1 in 1x3e Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Cadmium in the PDB 1x3e.
