[1] Curli formation is especially efficient at evading the host's immune system due to the subunits being able to quickly assemble in a single process and not having intermediates.
This system is associated with curli-specific genes and utilizes multiple proteins in its process to form curli fibers.
In pathogenic bacteria, curlis can contribute to virulence by helping in cell invasion and activating the innate immune response.
[1] Curli biogenesis is an adaptable process that uses a direct route and can transform from an intrinsically disordered complex system to a simple amyloid state.
Energy within a bacterial cell is typically supplied by ATP or GTP, proton motive force, or other membrane potentials.
However, with type VIII secretions systems, it is unlikely that energy is derived from one of these typical methods due to its location on the outer membrane of gram-negative bacteria.
