WebJun 7, 2011 · This suggests a potential chaperone-like role for CsgE with respect to CsgA. 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 ... WebAug 30, 2024 · We therefore hypothesize that the CsgA steric zipper spine segments contribute to the structured core of the CsgA fibril and allow for the formation of cross-β fibrils by full-length CsgA [2, 37, 39, 41]. Cross-β ultra-stable structures have been mechanically characterized to be as stiff as silk and as strong as steel .

Enteric bacteria produce functional amyloid fibers called curli that aid in biofilm formation and host … WebWe suggest a structural mechanism of the interaction between CsgE and CsgA. Understanding curli formation can provide the information necessary to develop …
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. WebFeb 26, 2024 · Although residue pairs at the interface vary between different dimer set-ups, the interaction energies for each case are, on average, similar (−5.3 ± 4.3 kcal/mol for CsgA–CsgA vs −4.6 ± 4 ...
