Bi nuclear iron complexes in met hem erythrin and azido met hem erythrin at 2.0 angstrom resolution

Journal of the American Chemical Society 106(3): 618-622
Bi nuclear iron complexes in met hem erythrin and azido met hem erythrin at 2.0 angstrom resolution
The binuclear Fe compelxes in methemerythrin and azidomethemerythin are compared and discussed. In methemerythrin, the complex consists of an octahedral Fe atom and a trigonal-bipyramidal Fe. The ligating atoms are provided by the amino acid side chains and a bridging O atom. In converting to azidomethemerythrin, the pentacoordinate Fe becomes octahedrally coordinated with the azide ion as the 6th ligand. Binding of azide, in addition to changing the symmetry of the complex, causes changes in the bond lengths and angles in the metal center and conformational changes in the protein.
