Abstract
A nanosecond resolution laser-driven x-ray source has been used to perform a time-resolved, x-ray diffraction study of the purple membrane of the Halobacterium halobium. Alterations in diffraction patterns have been observed 1 ms after photostimulation, and are interpreted to show disorder of bacteriorhodopsin packing in the plane of the membrane with little bacteriorhodopsin structural change.
摘要
一个具有纳秒分辨率的激光驱动X射线源已被用于对嗜盐菌紫膜进行时间分辨X射线衍射研究。在光刺激后1毫秒观察到衍射图案的变化，这些变化被解释为表明细菌视紫红质在膜平面内的堆积无序，而细菌视紫红质的结构变化很小。
