    • The present invention relates to a method of solving a phase by using zinc. More specifically, the present invention comprises: a step of contacting foreign zinc to a protein not having a zinc binding point; a step of irradiating an x-ray to the protein and foreign zinc; and a step of observing an anomalous signal of foreign zinc. The present invention originally does not have zinc, thus enables an x-ray analysis of a heavy element by contacting foreign zinc to the protein in which x-ray analysis of heavy element was impossible. Therefore, the present invention expands drastically a range of protein enabling the x-ray analysis of the heavy element, allows to analyze nearly all protein, easily reveals structures of the protein, and can facilitate the analysis of the heavy element of a pre-crystallized protein.
    • 本发明涉及通过使用锌来求解相的方法。 更具体地说,本发明包括:使外来锌与不具有锌结合点的蛋白质接触的步骤; 将X射线照射到蛋白质和外来锌的步骤; 并观察外来锌异常信号的一个步骤。 本发明最初不具有锌,因此能够通过使外来的锌与不可能重元素的X射线分析的蛋白质接触而对重元素进行x射线分析。 因此,本发明大幅度地扩展了能够进行重元素的X射线分析的蛋白质的范围,允许分析几乎所有的蛋白质,容易地揭示蛋白质的结构,并且可以促进对预结晶的重元素的分析 蛋白。
