description: This is a family of bactofilins, a functionally diverse class of cytoskeletal, polymer-forming,
  proteins that is widely conserved among bacteria. In the example species C. crescentus, two bactofilins
  assemble into a membrane-associated laminar structure that shows cell-cycle-dependent polar localisation
  and acts as a platform for the recruitment of a cell wall biosynthetic enzyme involved in polar morphogenesis.
  Bactofilins display distinct subcellular distributions and dynamics in different bacterial species,
  suggesting that they are versatile structural elements that have adopted a range of different cellular
  functions.
