摘要: The Al site structure of serum transferrin and lactoferrin is investigated using X-ray absorption near edge (XANES) spectroscopy. K-edge spectra in the mono- dialuminum forms proteins have been recorded for first time. Our results show that aluminium ion hexa-coordinated an octahedral-like symmetry monoaluminum form, where only C-terminal binding saturated, has increased structural distortion around metal site.
