Four families of photosensors (i.e., rhodopsins, phytochromes, xanthopsins and cryptochromes) exist, which vary widely in the degree to which we understand the molecular basis of their activity. Some of their members are ideal model systems for studying the structure-function relation of proteins, and the role of dynamics therein. The photochemistry of photosensor activation is based upon the cis <--> trans isomerization of the chromophore. This configurational transition leads to the formation… CONTINUE READING
