| Research Abstract |
Sensory rhodopsin I from eubacterium Salinibacter ruber is the photo-censor for the bacterial photo-taxis. In this study the photo-reaction dynamics of this protein was studied by transient grating (TG) method. As the result, the presences of new photo-intermediates were identified in the photo-cycle of sensory rhodopsin I. In addition, the enthalpy differences of the intermediates were determined by TG method and we found that they are significantly affected by the binding and dissociation of chloride ion.
