G蛋白偶联受体和其他膜蛋白的X射线晶体学受到与生长足够大的晶体相关的困难的阻碍,这些晶体能够承受辐射损伤并在同步加速器源处产生高分辨率数据。在这里,我们使用X射线自由电子激光器(XFEL)与单独的50 fs持续时间的X射线脉冲,以尽量减少辐射损伤,并获得了一个高分辨率的室温结构的人血清素受体使用亚10 μm微晶生长在膜模拟矩阵称为立方相。与通过传统的微晶学从约两个数量级大体积的低温冷却晶体中解决的结构相比,室温XFEL结构显示出不同的热运动分布和残基的构象,这可能更准确地代表细胞环境中的受体结构和动力学。
X-ray crystallography of G protein-coupled receptors and other membrane proteins is hampered by difficulties associated with growing sufficiently large crystals that withstand radiation damage and yield high-resolution data at synchrotron sources. Here we used an x-ray free-electron laser (XFEL) with individual 50-fs duration x-ray pulses to minimize radiation damage and obtained a high-resolution room temperature structure of a human serotonin receptor using sub-10 µm microcrystals grown in a membrane mimetic matrix known as lipidic cubic phase. Compared to the structure solved by traditional microcrystallography from cryo-cooled crystals of about two orders of magnitude larger volume, the room temperature XFEL structure displays a distinct distribution of thermal motions and conformations of residues that likely more accurately represent the receptor structure and dynamics in a cellular environment.
