New trisdipicolinic acid–lanthanide complexes are reported as phasing agents for X-ray crystallography of proteins. It is demonstrated that CuAAC modifications allow protein co-crystallization with low concentration of lanthanide complexes leading to an accurate structure determination.
据报道,新的三二olinic酸-
镧系元素复合物可作为蛋白质 X 射线晶体学的相位剂。研究表明,Cu
AAC 修饰物能使蛋白质与低浓度的
镧系配合物共晶,从而实现精确的结构测定。
