Abstract

Recently, LEWIS has proposed a molecular mechanism of excitation in visual transduction and bacteriorhodopsin [1]. There are three essential elements in this mechanism:

(1)
Vertical excitation of the retinal chromophore produces electron density rearrangement.
(2)
A bond rearrangement in the protein lowers the energy of this excited retinal-protein complex.
(3)
Torsional motion and rearrangement of the chromophore couples the molecule back onto the ground state surface and stabilizes the new protein conformation.
