Abstract excerpt

The early steps in the photocycle of sensory rhodopsin II mutant D75N are investigated in a comprehensive study using femtosecond visible pump/probe spectroscopy. An overall slower response dynamics after photoexcitation is observed compared to wild-type sensory rhodopsin II, which is assigned to changed electrostatics and an altered hydrogen-bonding network within the retinal binding pocket. Furthermore, the...
