W. Lu et al., PROTEIN SECONDARY STRUCTURE OF PHOTOSYSTE M-II REACTION-CENTER STUDIED BY FTIR SPECTROSCOPY, JOURNAL OF INFRARED AND MILLIMETER WAVES, 17(1), 1998, pp. 66-70
The secondary structure of the isolated photosystem II (PS II) reactio
n center was characterized by Fourier transform infrared (FTIR) spectr
oscopy. The recorded spectra show some difference between results of 3
00K and 77K for the amide I band, which is related with the secondary
structure of PS II, The main phenomenon is the transfer of infrared ab
sorption between the beta-sheets and turns related absorption bands.
