EXAFS spectra of the dicopper and monocopper complexes of human serum transferrin have been recorded and compared to those of the native iron derivative. The experimental data have been analyzed by comparison with EXAFS data obtained from copper(II) model compounds. Evidence is provided for a more regular metal chromophore in copper transferrin with respect to native iron transferrin. No major intersite differences were observed. The results are discussed in light of the recently reported crystal structures of iron transferrins and copper lactoferrin.

Abstract
EXAFS spectra of the dicopper and monocopper complexes of human serum transferrin have been recorded and compared to those of the native iron derivative. The experimental data have been analyzed by comparison with EXAFS data obtained from copper(II) model compounds. Evidence is provided for a more regular metal chromophore in copper transferrin with respect to native iron transferrin. No major intersite differences were observed. The results are discussed in light of the recently reported crystal structures of iron transferrins and copper lactoferrin.
