abstract

  • The cytoplasmic C ring of the bacterial flagellum is known as the switch complex. It binds the response regulator phospho-CheY to control the direction of flagellar rotation. The C ring of enteric bacteria is well characterized. However, no Gram-positive switch complex had been modeled. Ward et al. (E. Ward, E. A. Kim, J. Panushka, T. Botelho, et al., J Bacteriol 201:e00626-18, 2019, https://doi.org/10.1128/JB.00626-18) propose a structure for the Bacillus subtilis switch complex based on extensive biochemical studies. The work demonstrates that a similar architecture can accommodate different proteins and a reversed signaling logic.
