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 ...
