拉曼光谱可以在很宽的时间尺度上提供关于蛋白质结构演变的独特信息;皮秒到毫秒的范围可以通过泵浦-探测技术来访问。通过将探针激光器调谐到共振电子跃迁(包括芳香族残基和肽键的UV跃迁)来询问分子的特定部分。激光技术的进步使瞬态物种的表征达到了前所未有的结构细节水平。综述了蛋白质去折叠和变构的研究进展。
Raman spectroscopy can provide unique information on the evolution of structure in proteins over a wide range of time-scales; the picosecond to millisecond range can be accessed with pump-probe techniques. Specific parts of the molecule are interrogated by tuning the probe laser to a resonant electronic transition, including the UV transitions of aromatic residues and of the peptide bond. Advances in laser technology have enabled the characterization of transient species at an unprecedented level of structural detail. Applications to protein unfolding and allostery are reviewed.
