摘要：
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 reveal new structural dynamics that occur in the timescale of similar to 360 picoseconds (ps) and similar to 9 nanoseconds (ns), which have not been clearly detected in previous studies.
