In a recent issue of Nature, Barends et al. studied the photodissociation of carboxymyoglobin with ultrafast laser pump-probe serial femtosecond crystallography experiments. They observed significant differences in heme protein structural dynamics for biologically relevant 1-photon excitation relative to high excitation leading to the absorption of several photons per heme.
在最近一期的《自然》杂志上,巴伦兹等人通过超快激光泵浦探测连续飞秒晶体学实验研究了羧基肌红蛋白的光解。他们观察到,对于生物学上相关的单光子激发,与导致每个血红素吸收几个光子的高激发相比,血红素蛋白结构动力学有显著差异。
