United KingdomResearchers from the University of Bayreuth and Forschungszentrum Jülich have discovered that light-sensitive bacterial enzymes called sensor histidine kinases (SHKs) transmit signals through a light-controlled change in asymmetry. Their study, published in Science Advances, reveals how these enzymes switch between two structural forms in response to light, providing critical insight into bacterial signaling mechanisms. SHKs are essential components of bacterial two-component systems, where they detect environmental stimuli like light and regulate cellular responses such as gene expression. The findings could lead to advancements in optogenetics, allowing scientists to more precisely control biological processes using light, with potential applications in biotechnology and medicine.
