LOV domains are protein photosensors conserved in bacteria, archaea, plants and fungi that detect blue light via a flavin cofactor. In the bacterial kingdom, LOV domains are present in both chemotrophic and phototrophic species, where they are found N-terminally of signaling and regulatory domains such as sensor histidine kinases, diguanylate cyclases/phosphodiesterases, DNA-binding domains, and σ factor regulators. In this review, we describe the current state of knowledge on the function of bacterial LOV proteins, the structural basis of LOV domain-mediated signal transduction, and the use of LOV domains as genetically-encoded photoswitches in synthetic biology.
