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]
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.

Effects of multiple cell regulators on curli gene expression in Escherichia coli [PDF]
Curli 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.

Structure-Function Analysis of the Curli Accessory Protein CsgE Defines Surfaces Essential for Coordinating Amyloid Fiber Formation [PDF]
Curli amyloid fibers are produced as part of the extracellular biofilm matrix and are composed primarily of the major structural subunit CsgA. The CsgE chaperone facilitates the secretion of CsgA through CsgG by forming a cap at the base of the nonameric

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

Cyclic‐di‐GMP signalling and biofilm‐related properties of the Shiga toxin‐producing 2011 German outbreak Escherichia coli O104:H4 [PDF]
In 2011, nearly 4,000 people in Germany were infected by Shiga toxin (Stx)‐producing Escherichia coli O104:H4 with > 22% of patients developing haemolytic uraemic syndrome (HUS).

Escherichia coli O157:H7 expresses extracellular proteins called curli that are essential for surface colonization. Transfer rates of E. coli O157:H7 0018+ (curli+), and 0018- (curli−) from inoculated to noninoculated lettuce pieces during washing were ...

AbstractThis letter reflects on my collaborations with Nick Martin over the past 18 years. Working together we have applied twin-family and statistical genetics methods to examine the genetic architecture and identify genetic variants influencing a range of physical, psychological and social traits.

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 functional amyloid systems are phylogenetically widespread and display large diversity in operon and protein structure. [PDF]
Escherichia coli and a few other members of the Enterobacteriales can produce functional amyloids known as curli. These extracellular fibrils are involved in biofilm formation and studies have shown that they may act as virulence factors during ...
