Abstract

We have observed Brillouin-like low frequency collective modes in the scattering of 1 A neutrons from a fully in vivo deuterated protein. These modes are tentatively interpreted as due to short-lived coherent excitations propagating with velocities between 2,000 and 4,000 m/s in elements of the secondary structure and patches of closely associated water.

摘要

我们在来自完全体内氘代蛋白质的1埃中子散射中观察到了类似布里渊的低频集体模式。这些模式初步解释为是由于在二级结构单元和紧密相连的水区域中以2000至4000米/秒的速度传播的短寿命相干激发所致。
