摘 要: | 同步辐射的发展和应用已经极大的推动了自然科学包括生物学的巨大发展,其中结构生物学更是离不开X射线衍射分析,小角散射等。X射线自由电子激光(XFEL)相比同步辐射具有更高强度,完全相干等特点,被称为第四代光源。科学家已经利用XFEL实现了尺度约为1微米的蛋白质晶体的高分辨率结构解析,并且也实现了单颗粒的病毒的低分辨重构。未来,XFEL将会为生物学的发展打开一扇新的大门。

Abstract: | The application of synchrotron radiation has a great progress on biological research. And structur- al biology relies heavily on X-ray diffraction and small angle X-ray scattering. X-ray free electron laser (XFEL) will generate extremely intense and coherent X-ray flashes. Using 1 micron size crystals, protein structure has been successfully solved by XFEL at high resolution. High quality diffraction data was obtained with XFEL from a single virus particle and low resolution structure map was reconstructed. XFEL will be expected to open the new field of biological research. |
