Cadmium in the structure of Recombinant Horse L-Chain Apoferritin N-Terminal Deletion Mutant (Residues 1-8) (pdb 2za8)

The binding sites of Cadmium atom in the structure of Recombinant Horse L-Chain Apoferritin N-Terminal Deletion Mutant (Residues 1-8) (pdb code 2za8). This binding sites where shown with 5.0 Angstroms radius around Cadmium atom. The 2za8 structure was solved by I.YAMASHITA, Y.MISHIMA, S.-Y.PARK, J.G.HEDDLE, J.R.H.TAME, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 19.8-1.4 Space group F432 a (A) 180.210 b (A) 180.210 c (A) 180.210 alpha (°) 90.00 beta (°) 90.00 gamma (°) 90.00 Rfactor (%) 22 Rfree (%) 23.9 Cadmium Binding Sites: Cadmium binding site 1 out of 2 in 2za8 Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Cadmium in the PDB 2za8.
