Paper Abstract

The photocycle of the 4-keto bacteriorhodopsin is investigated. We constructed a multilevel theoretical model for the transmittance properties of the material. Adjusting the relaxation parameters we are able to fit the theoretical intensity dependent transmittance curves into the experiments. Thus we determine the photocycle from simple optical measurements. This method provides a new approach for studying light-induced changes in photochromic proteins.
