[Surface photovoltaic spectroscopic investigation of Bacteriorhodopsin (BR)].
The surface photovoltaic spectra (SPS) of Bacteriorhodopsin-based films were systematically measured. The results show that the BR films are characterized by the specific photovoltaic effect. The SPS response of the BR films depends on the fabrication and humidity of the film. The intermediate M412 and O640 of BR are observed in the SPS of HEPES-containing BR film, indicating that HEPES has very important function to stabilize intermediate M412. The observations are explained in terms of the photocycle of BR and the mechanism of photovoltage generation.
