在这里,我们报道了马肌红蛋白(Mb)对皮秒时间分辨X射线溶液散射显示的CO光解的响应的结构动力学。这些数据清楚地揭示了在~360皮秒(Ps)和~9纳秒(Ns)的时间尺度上发生的新的结构动力学,这在以前的研究中没有被清楚地检测到。
Here we report structural dynamics of equine myoglobin (Mb) in response to the CO photodissociation visualized by picosecond time-resolved X-ray solution scattering. The data clearly reveals new structural dynamics that occurs in the timescale of ~360 picoseconds (ps) and ~9 nanoseconds (ns), which have not been clearly detected in previous studies.
