Picosecond events in the photochemical cycle of the light-driven chloride-pump halorhodopsin.

H J Polland, M A Franz, W Zinth, W Kaiser, P Hegemann, D Oesterhelt.   

Abstract

The early events in halorhodopsin after light excitation are studied with picosecond time resolution. Absorption and fluorescence measurements show that the electronically excited state of the incorporated retinal has a lifetime of 5 ps. Within that time a red-shifted photoproduct is formed that remains stable for at least 2 ns.
