The photon-driven proton translocator bacteriorhodopsin is considered to be the best understood membrane protein so far. It is nowadays regarded as a model system for photosynthesis, proton pumps and seven transmembrane receptors. The profound knowledge come from the applicability of a variety of modern biophysical techniques which are being been further developed for the research on bacteriorhodopsin and resulted in major contributions also to other areas. Most prominent examples are fourier transform infrared spectroscopy, resonance Raman spectroscopy, solid-state NMR spectroscopy and time-resolved vibrational spectroscopy. The achievement in spectral analysis results will strongly advance our understanding of the photoelectric characteristics of bacteriorhodopsin. And it will have application in light-induced color changing, instant photoelectricity response, nonlinear optical capability and so on.
