Scientists have revealed the three-dimensional structure of Flycatcher1, an aptly named protein channel that may enable Venus fly trap plants to snap shut in response to prey. The structure of Flycatcher1 helps shed light on longstanding questions about the remarkably sensitive touch response of Venus fly traps. The structure also gives the researchers a better understanding of how similar proteins in organisms including plants and bacteria, as well as proteins in the human body with similar functions (called mechanosensitive ion channels), might operate.
