Bacteria can rapidly and reversibly respond to changing environments via complex
transcriptional and post-transcriptional regulatory mechanisms. Many of these adaptations …

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 …

Conditions that sustain constant bacterial growth are seldom found in nature. Oligotrophic
environments and competition among microorganisms force bacteria to be able to adapt …

The cross-species bacterial communication signal autoinducer 2 (AI-2), produced by the
purified enzymes Pfs (nucleosidase) and LuxS (terminal synthase) from S …

Many bacteria assemble extracellular amyloid fibers on their cell surface. Secretion of
proteins across membranes and the assembly of complex macromolecular structures must …

Biofilms of enteric bacteria are highly complex, with multiple components that interact to
fortify the biofilm matrix. Within biofilms of enteric bacteria such as Escherichia coli and …

During the transition from post-exponential to stationary phase, Escherichia coli changes
from the motile-planktonic to the adhesive-sedentary “lifestyle.” We demonstrate this …

Early work identified two promoter regions, the− 10 and− 35 elements, that interact
sequence specifically with bacterial RNA polymerase (RNAP). However, we now know that …

In natural habitats, bacteria often occur in multicellular communities characterized by a
robust extracellular matrix of proteins, amyloid fibres, exopolysaccharides and extracellular …

Curli fibers could be described as a virulence factor able to confer adherence properties to
both abiotic and eukaryotic surfaces. The ability to adapt rapidly to changing environmental …
