WebJul 24, 2007 · In a simple model of curli formation, the major curli subunit CsgA is secreted from the cell as a soluble, unpolymerized protein. CsgA would remain unpolymerized unless it contacts a CsgB-expressing cell. In a process called nucleation, CsgB mediates the conversion of CsgA from a soluble protein to an insoluble fiber. WebAlthough CsgA is prone to aggregation and forms amyloid fibers in vitro (2, 27), the formation of curli fibers in vivo is nucleated by CsgB (28–30). CsgC exists in periplasm and is an effective inhibitor of CsgA polymerization, suppressing fibrilization at substoichiometric ratios as low as 1:500 (CsgC:CsgA) ( 31 ), and perhaps preventing ...

If biologically relevant, this activity in vivo could ensure that secretion of soluble CsgA precedes fibre formation, thereby preventing formation of periplasmic amyloid oligomers or fibres and abrogating intracellular amyloid toxicity. This activity would also promote ... WebCsgA, which makes up the fibril, and CsgB, which anchors the fibril to the cell membrane. The rate-limiting steps are nucleation and elongation. Nucleation is mostly referring to a CsgB peptide attaching to the cell membrane, enabling the formation of a new fibril, but can also refer to two CsgA monomers coming together to form a freely ... fishy full screen
