title: The piston rises again.
abstract: Previous evidence has indicated that the transmembrane signal in bacterial chemoeceptors is carried by the piston displacement of a membrane-spanning signaling helix. Hendrickson and coworkers (Cheung and Hendrickson, 2009; Moore and Hendrickson, 2009) now provide structural evidence that suggests piston transmembrane signaling is widely conserved in bacterial receptors that control ubiquitous two-component signaling pathways.
