Nonpolymer-forming landmark proteins. (A) The domain structure of TipN is indicated with transmembrane domains in black and a coiled-coil region in red. Bottom: localization of TipN and associated proteins during the cell cycle including the ParABS-dependent chromosome segregation process and with the old and new poles marked. c-di-GMP levels in different cell types are indicated as high (upward arrow) and low (downward arrow). Flagellum and pili are indicated at the nonstalked pole. (B) The domain structure of PodJ is indicated with coiled-coil regions in red, a transmembrane domain in black, three TPR domains in gray, and the peptidoglycan binding muramidase domain in yellow. Bottom: localization of PodJ and associated proteins during a cell cycle. Flagellum and pili are indicated at the nonstalked pole. (C) The domain structure of HubP is indicated with the LysM peptidoglycan-binding domain in yellow, a transmembrane domain in black, and the repeat rich region in red. Bottom: localization of HubP and associated proteins during a cell cycle including the chromosome segregation process, the flagellum, and the array of chemotaxis proteins.
