Effects of multiple cell regulators on curli gene expression in Escherichia coli [PDF]
Journal of BacteriologyCurli amyloid fibers are the key protenacious component of the extracellular matrix in Escherichia coli. The regulation of curli expression is highly complex and depends on multiple environmental responses.

Absence of Curli in Soil-Persistent Escherichia coli Is Mediated by a C-di-GMP Signaling Defect and Suggests Evidence of Biofilm-Independent Niche Specialization [PDF]
Frontiers in Microbiology, 2018 Escherichia coli is commonly viewed as a gastrointestinal commensal or pathogen although an increasing body of evidence suggests that it can persist in non-host environments as well.

PLoS Genetics, 2023 Curli amyloid fibers are a major constituent of the extracellular biofilm matrix formed by bacteria of the Enterobacteriaceae family. Within Escherichia coli biofilms, curli gene expression is limited to a subpopulation of bacteria, leading to ...

Curli of Uropathogenic Escherichia coli Enhance Urinary Tract Colonization as a Fitness Factor
Frontiers in Microbiology, 2019 Curli, a type of fimbriae widely distributed in uropathogenic Escherichia coli (UPEC), are involved in adhesion to human bladder cell surfaces and biofilm development. The role of UPEC curli was evaluated in a murine model of urinary tract infection. The

Assembly and substrate recognition of curli biogenesis system
Nature Communications, 2020 A major component of bacterial biofilms is curli amyloid fibrils secreted by the curli biogenesis system. Here authors use cryo-EM to visualize the secretion channel complexes (CsgF-CsgG) with and without the curli substrate and provide insights into ...

Bacterial curli protein promotes the conversion of PAP248-286 into the amyloid SEVI: cross-seeding of dissimilar amyloid sequences [PDF]
PeerJ, 2013 Fragments of prostatic acid phosphatase (PAP248-286) in human semen dramatically increase HIV infection efficiency by increasing virus adhesion to target cells.

Curli Biogenesis and Function [PDF]
Annual Review of Microbiology, 2006 Curli are the major proteinaceous component of a complex extracellular matrix produced by many Enterobacteriaceae. Curli were first discovered in the late 1980s on Escherichia coli strains that caused bovine mastitis, and have since been implicated in many physiological and pathogenic processes of E. coli and Salmonella spp.

Biomolecules, 2018 Escherichia coli strains may be beneficial or pathogenic. Many E. coli strains that cause human disease, especially those responsible for bacteremia and sepsis, express virulence factors that impart resistance to the complement system.

The Production of Curli Amyloid Fibers Is Deeply Integrated into the Biology of Escherichia coli
Biomolecules, 2017 Curli amyloid fibers are the major protein component of the extracellular matrix produced by Enterobacteriaceae during biofilm formation. Curli are required for proper biofilm development and environmental persistence by Escherichia coli.
