Iron in the structure of X-Ray Structure of the Fefe-Hydrogenase Maturase Hyde From T. Maritima in Complex With Methionine and 5'Deoxyadenosine (pdb 3iix)

The binding sites of Iron atom in the structure of X-Ray Structure of the Fefe-Hydrogenase Maturase Hyde From T. Maritima in Complex With Methionine and 5'Deoxyadenosine (pdb code 3iix). This binding sites where shown with 5.0 Angstroms radius around Iron atom. The 3iix structure was solved by Y.NICOLET, P.AMARA, J.M.MOUESCA, J.C.FONTECILLA-CAMPS, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 58.2-1.2 Space group P212121 a (A) 51.054 b (A) 78.925 c (A) 86.192 alpha (°) 90.00 beta (°) 90.00 gamma (°) 90.00 Rfactor (%) 13.9 Rfree (%) 16.6 Iron Binding Sites: Iron binding site 1 out of 4 in 3iix Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Iron in the PDB 3iix.
