(Figure Presented) Glowing after a sugar rush: A molecular switch is formed by inserting glucose-binding protein (GBP) into aequorin (AEQ; see picture). This switch is triggered by recognition of glucose by the GBP. For the first time, AEQ is rationally split into two fragments that, upon a molecular recognition event, come together and emit bioluminescence.
