Abstract:
:Exposure of aqueous suspensions of fragments of the purple membrane of Halobacterium halobium to electric field pulses leads to transient linear dichroism phenomena. The effects are interpreted in terms of field-induced alignments of the bacteriorhodopsin chromophore. Two observed relaxation times (tau) are attributed to rotation of the whole membrane fragments (tau s approximately 100 ms), and to a much faster reorientation of the chromophore within membrane (tau f approximately 260 microns).
