Ultrafast Studies of the Photophysics of Cis and Trans States of the Green Fluorescent Protein Chromophore

Cis–trans photoisomerization is proposed as a key process in the photoswitching of some photoactivatable fluorescent proteins. Here we present ultrafast fluorescence measurements of the model GFP chromophore (HBDI) in the cis state and in a mixture of the cis and trans states. Our results demonstrate that the mean lifetimes of the cis and trans states are remarkably similar. Therefore, the specific isomer of the chromophore cannot be solely responsible for the different photophysics of the bright and dark states of photoactive proteins, which must therefore be due to differential interactions between the different isomers of the chromophore and the protein
