Infrared evidence that the Schiff base of bacteriorhodopsin is protonated: bR570 and K intermediates.
It is possible, by using Fourier-transform infrared (FTIR) difference spectroscopy, to detect the conformational changes occurring in both the protein and the chromophore of bacteriorhodopsin during the photocycle. In contrast to Raman spectroscopy, a laser is unnecessary and hence the problem of a...
