English Abstract

A successful study on the secondary structure of the isolated photosystem Ⅱ (PSⅡ) particles with the Fourier transform infrared spectroscopy is reported in this paper. The β condensation effect is obviously charactetized by infrared absorption spectra. The infrared of both living protein and β condensed protein samples are measured at room temperature. The amide Ⅰ band in infrared spectrum in used to perform the quantitative analysis of the sample properties. The recorded spectra show the irreversible effect for the PSⅡ particles after the 400 K heating. A rather strong change of the infrared spectra is observed due to the β condensation of PSⅡ protein. All the spectra are well fitted by 3-Lorentz-peak. The FTIR spectroscopy shows its effectiveness in studying the heating effect on the PSⅡ particles.
