Orientation of the chromophore plane in purple membrane.

A Dér, S Száraz, J Czégé.   

Abstract

Excitation of bacteriorhodopsin (BR) in its beta absorption band drives a photocycle identical in the millisecond range, to that excited in the alpha band of BR. The relative contribution of the two transition dipoles distinguished in the beta band to the initiation of the photocycle was established by photoselection experiments. Having this information the orientation of the chromophoric plane was specified by electric dichroism measurements.
