Short runs of adenines are a ubiquitous DNA element in regulatory regions of many
organisms. When runs of 4–6 adenine base pairs ('A-tracts') are repeated with the helical …

Temperature is among the most important of the parameters that free-living microbes
monitor. Microbial physiology needs to be readjusted in response to sudden temperature …

Horizontal DNA transfer plays a major role in the evolution of bacteria. It allows them to
acquire new traits rapidly and these may confer fitness advantages as the bacteria compete …

Introduction 3. Islands of horizontally-acquired DNA 4. Regulating the expression of laterally-
acquired genes 4.1. Repression of horizontally-acquired genes 4.2. Activating H-NS …

The molecular determinants necessary and sufficient for recognition of its specific DNA
target are contained in the C-terminal domain (H-NSctd) of nucleoid-associated protein H …

Escherichia coli group 2 capsule gene clusters are temperature regulated, being expressed
at 37° C but not at 20° C. Expression is regulated at the level of transcription by two …

In their natural habitats, bacteria are frequently exposed to sudden changes in temperature.
It has been shown that bacteria use different strategies to cope with temperature changes …

Shigella species and enteroinvasive Escherichia coli possess a large virulence plasmid that
carries the genes necessary for invasion and colonization of the epithelial cell layer of the …

The advancement in Escherichia coli genome research has made the information regarding
transcription start sites of many genes available. A study relying on the availability of …

The DNA static curvature has been described to play a key role as a regulatory element in
the transcription process of several bacterial genes. Here, the role of DNA curvature in the …
