Dr. Ebrey is studying light energy transduction in the purple                   membrane of Halobacterium halobium.  A variety of physical                      techniques will be used to investigate its only pigment,                        bacteriorhodopsin (BR) and its photocycle intermediates.                                                                                                        The purple membrane is a particularly simple biological                         light-energy transducer.  A great deal is known about the                       structure of both BR and the purple membrane.  A broad attack                   on the problem of how light causes the pumping of protons                       across the cell membrane is planned.  The key to this problem                   is to understand the interrelationships between the structure                   of both the chromophore and the protein part of                                 bacteriorhodopsin, the photochemistry that occurs when the                      chromophore absorbs a photon and the movement of protons                        across the cell membrane.  The well-defined nature of the                       problem of relating proton pumping activity, the                                photochemistry of the purple membrane and the structure of BR                   make it an extremely important area of study in biology                         today.***//
