摘要
(Figure Presented) Molecular light-switch: Off-on switching of the fluorescence of the protein asFP595 involves a trans-cis isomerization. Mixed quantum/classical simulations elucidate the spectroscopic properties of asFP595 and give detailed insights into the photoswitching mechanism. The conformational trans-cis switching triggers a proton-transfer cascade between the chromophore and adjacent amino acids. © 2007 Wiley-VCH Verlag GmbH & Co. KGaA.
