摘要We demonstrate the applications of terahertz time-domain spectroscopy to distinguish conformation changes of the chlorophyll proteins CP43 and CP47 induced by the treatment of guanidine hydrochloride, light irradiation and heating. It is indicated that THz transmission spectroscopy can be used for monitoring protein denaturation and associated conformation change processes in a feasible and effective way.
