以碲为中心的安德森-埃文斯多钨酸盐[TeW 6 O 24]6-(TEW)作为结晶添加剂的用途已经被描述。在这里,我们提出了使用TEW作为添加剂在热休克蛋白70的核苷酸结合域(NBD)的结晶筛选。在不存在TEW的情况下,使用标准商业筛选对HSP 70 NBD进行结晶筛选,得到单晶形式。在TEW存在下HSP 70 NBD的相同结晶筛选产生“不含TEW”的晶型和具有不同晶体堆积的另外的晶型。在两种晶体形式中均观察到TEW结合,无论是作为明确定义的分子还是在重叠的交替位置,表明翻译障碍。用分子置换和单波长反常衍射(SAD)方法,利用TEW单个结合分子的反常信号,解析了结构。这项研究增加了一个TEW结合蛋白质并影响其结晶行为的例子。
The use of the tellurium-centered Anderson−Evans polyoxotungstate [TeW6O24]6− (TEW) as a crystallization additive has been described. Here, we present the use of TEW as an additive in the crystallization screening of the nucleotide binding domain (NBD) of HSP70. Crystallization screening of the HSP70 NBD in the absence of TEW using a standard commercial screen resulted in a single crystal form. An identical crystallization screen of the HSP70 NBD in the presence of TEW resulted in both the “TEW free” crystal form and an additional crystal form with a different crystal packing. TEW binding was observed in both crystal forms, either as a well-defined molecule or in overlapping alternate positions suggesting translational disorder. The structures were solved by both molecular replacement and single wavelength anomalous diffraction (SAD) using the anomalous signal of a single bound molecule of TEW. This study adds one more example of TEW binding to a protein and influencing its crystallization behavior.
