Electrostatic interactions mediate the nucleation and growth of a bacterial functional amyloid.

Bacterial biofilm formation can have severe impacts on human and environmental health. Enteric bacteria produce functional amyloid fibers called curli that aid in biofilm formation and host colonization. CsgA is the major proteinaceous component of curli amyloid fibers and is conserved in many gram-negative enteric bacteria.

Mechanistic insights into accelerated α-synuclein aggregation mediated by human microbiome-associated functional amyloids.

The gut microbiome has been shown to have key implications in the pathogenesis of Parkinson's disease (PD). The Escherichia coli functional amyloid CsgA is known to accelerate α-synuclein aggregation in vitro and induce PD symptoms in mice. However, the mechanism governing CsgA-mediated acceleration of α-synuclein aggregation is unclear.

Curli Biogenesis: Bacterial Amyloid Assembly by the Type VIII Secretion Pathway.

In 1989, Normark and coworkers reported on fibrous surface structures called curli on strains of that were suspected of causing bovine mastitis. Subsequent work by many groups has revealed an elegant and highly regulated curli biogenesis pathway also referred to as the type VIII secretion system. Curli biogenesis is governed by two divergently transcribed operons, and .
