Edge evidence

  • bacterial-type flagellum defines lophotrichous METPO:2007500

    A tuft of flagella at one pole defines the lophotrichous arrangement.

    • DOI:10.1093/femsre/fuv034 Schuhmacher et al. describe polar tufts of flagella (lophotrichous).
  • lophotrichous associated with polar tuft placement biolink:associated_with

    The lophotrichous pattern places multiple flagella at one pole.

    • DOI:10.3390/biom9070279 Flagellum review supports multiple flagellar filaments acting as locomotory organelles.
  • FlhF localizes to and promotes assembly at cell pole

    GTP-bound FlhF localizes to the cell pole and recruits initial flagellar building blocks.

    • DOI:10.7554/eLife.93004.3 GTP-bound dimeric FlhF localizes to the cell pole and recruits initial flagellar building blocks; deletion of flhF causes absence/mislocalization of flagella.
  • FlhF recruits FliG

    FlhF binds the C-ring protein FliG to initiate polar assembly.

    • DOI:10.1038/s41467-024-50274-4 FlhF binds the C-ring protein FliG via its N-terminus.
  • FliG captures FliF

    The FlhF:FliG complex recruits/captures FliF to promote MS-ring formation at the pole.

    • DOI:10.7554/eLife.93004.3 FliG captures FliF to promote MS-ring formation; recruits a functional FliF/FliG complex to the pole.
  • FipA required for lophotrichous

    FipA is required for normal FlhF activity and polar flagellar synthesis.

    • DOI:10.7554/eLife.93004.3 FipA is required for normal FlhF activity and polar flagellar synthesis; deletion abolishes swimming motility and yields cells lacking surface flagella.
  • FlhG negatively regulates flagellar number

    FlhG limits flagellar number; its loss causes hyper-flagellation.

    • DOI:10.1093/femsre/fuv034 Loss of FlhG causes hyper-flagellation; deletion of flhG produces hyper-flagellated strains.
  • FlhG stimulates GTPase activity of FlhF

    FlhG stimulates the GTPase activity of FlhF, converting GTP-bound to GDP-bound FlhF.

    • DOI:10.1038/s41467-024-50274-4 FlhG stimulates the GTPase activity of the SRP-type GTPase FlhF, converting GTP-bound FlhF to GDP-bound FlhF.
