The coupling of sensory modules with enzymatic effectors allows direct allosteric regulation of cellular signaling molecules in response to diverse stimuli. We present molecular details of red light-sensing bacteriophytochromes linked to cyclic dimeric guanosine monophosphate-producing diguanylyl cyclases. Elucidation of the first crystal structure of a full-length phytochrome with its enzymatic effector, in combination with the characterization of light-induced changes in conformational dynamics, reveals how allosteric light regulation is fine-tuned by the architecture and composition of the coiled-coil sensor-effector linker and also the central helical spine. We anticipate that consideration of molecular principles of sensor-effector coupling, going beyond the length of the characteristic linker, and the appreciation of dynamically driven allostery will open up new directions for the design of novel red light-regulated optogenetic tools.
