flagellar arrangement

traitmech:000056 · CLASS · REVIEWED

A morphology trait describing the number and spatial distribution of flagella on a cell (the flagellation pattern), e.g. monotrichous, lophotrichous, amphitrichous, or peritrichous.

Edge evidence

  • bacterial-type flagellum defines flagellar arrangement METPO:2007500

    The cellular distribution of flagella defines the arrangement.

    • DOI:10.3390/biom9070279 Bacterial flagellum review supports the flagellum as the locomotory organelle whose number and placement define the arrangement.
  • FlhF/FlhG flagellar placement regulation regulates flagellar arrangement RO:0002211

    FlhF/FlhG set the species-specific flagellation pattern.

    • DOI:10.1093/femsre/fuv034 Schuhmacher et al. describe FlhF/FlhG governance of the flagellation pattern.
  • FlhG stimulates GTPase activity of FlhF

    FlhG stimulates the GTPase activity of FlhF, a conserved core regulatory interaction governing flagellar placement.

    • DOI:10.1038/s41467-024-50274-4 Dornes 2024: "FlhG acts on FlhF by stimulating its GTPase activity" - conserved core regulatory edge.
  • FlhF directs to cell pole FliF (MS-ring protein)

    FlhF is required to direct the initial MS-ring protein FliF to the cell pole, nucleating basal-body assembly.

    • DOI:10.1038/s41467-024-50274-4 Dornes 2024: "FlhF... is required to direct the initial MS-ring protein FliF to the cell pole."
  • FlhF binds FliG

    FlhF binds FliG, coupling the placement regulator to C-ring/MS-ring assembly.

    • DOI:10.1038/s41467-024-50274-4 Dornes 2024: FlhF B-domain (FliG Interaction Domain) is necessary and sufficient for FliG binding.
  • FliG engages / recruits FliF (MS-ring protein)

    FlhF-bound FliG engages the MS-ring protein FliF, recruiting a FliF-FliG complex to the pole.

    • DOI:10.1038/s41467-024-50274-4 Dornes 2024: "FlhF-bound FliG then engages the MS-ring protein FliF, recruiting a FliF-FliG complex to the pole."
  • FlhF establishes marking of future flagellar assembly site

    FlhF marks the future flagellar assembly site, after which basal-body assembly proceeds.

    • DOI:10.1093/femsre/fuv034 Schuhmacher 2015: "After FlhF marked the future flagellar site, assembly of the basal body will proceed."
  • marking of future flagellar assembly site occurs at cell pole

    The marking of the future flagellar assembly site localizes basal-body building blocks to the cell pole.

    • DOI:10.1093/femsre/fuv034 Schuhmacher 2015: FlhF B-domain recruits MS-ring component FliF to the cell pole.
