Abstract excerpt

Phoborhodopsin from Halobacterium salinarum (salinarum phoborhodopsin, spR also called HsSR II) is a photoreceptor for the negative phototaxis of the bacterium. A unique feature of spR is the formation of a shorter wavelength photoproduct, P480, observed at liquid nitrogen temperature beside the K intermediate. Formation of similar photoproduct has not been reported in the other microbial rhodopsins. This...
