The binding sites of Iron atom in the structure of High-Resolution X-Ray Study of Deoxy Recombinant Human Hemoglobins Synthesized From Beta-Globins Having Mutated Amino Termini (pdb code 1dxv). This binding sites where shown with 5.0 Angstroms radius around Iron atom. The 1dxv structure was solved by J.S.KAVANAUGH, A.ARNONE, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 6.0-1.7 Space group P1211 a (A) 63.200 b (A) 83.600 c (A) 53.800 alpha (°) 90.00 beta (°) 99.30 gamma (°) 90.00 Rfactor (%) n/a Rfree (%) n/a Iron Binding Sites: Iron binding site 1 out of 4 in 1dxv Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Iron in the PDB 1dxv.
