利用X射线吸收近边结构(XANES)谱研究了血清转铁蛋白和乳铁蛋白的铝位结构。铝K-边缘光谱的单和二铝形式的蛋白质已被记录的第一次。我们的研究结果表明,铝离子是六配位的八面体状对称性和单铝的形式,其中只有C-末端结合位点是饱和的,有一个增加的结构扭曲周围的金属网站。
The Al site structure of serum transferrin and lactoferrin is investigated using X-ray absorption near edge structure (XANES) spectroscopy. Al K-edge spectra in the mono- and dialuminum forms of the proteins have been recorded for the first time. Our results show that the aluminium ion is hexa-coordinated in an octahedral-like symmetry and that the monoaluminum form, where only the C-terminal binding site is saturated, has an increased structural distortion around the metal site.
