Abstract excerpt
Predicting mutation-induced photophysical changes in bilin-binding fluorescent proteins remains challenging. Here, we investigate the origin of fluorescence modulation in smURFP and its low-fluorescent-quantum-yield Y56R variant using classical MD simulations and QM/MM calculations. Comparison of multiple chromophore binding states supports a wild-type configuration involving A-ring attachment and chromophore...
