The main components of the prokaryotic chemotaxis system, chemoreceptors, organize into a hexagonal (P6 symmetry) extended array. Here authors use cryo-ET and report an alternative symmetry (P2) of the chemotaxis apparatus that emerges from a strict linear organization of the histidine kinase CheA in Treponema denticola cells.
