Abstract

Sensory photoreceptors underpin diverse adaptive responses in nature and serve as genetically encoded, light-gated actuators in optogenetics. Photoactivated nucleotide cyclases (PACs) enable light-dependent control over the formation of cyclic nucleotides (cNMPs). Conversely, the engineered, red-light-activated phosphodiesterase LAPD mediates the hydrolytic breakdown of cNMPs. In combination, PACs and LAPD hence unlock precise and graded control over intracellular cNMPs and associated processes.
