The LysR family of transcriptional regulators represents the most abundant type of
transcriptional regulator in the prokaryotic kingdom. Members of this family have a …

Redox reactions pervade living cells. They are central to both anabolic and catabolic
metabolism. The ability to maintain redox balance is therefore vital to all organisms. Various …

Marine and terrestrial photosynthetic and chemoautotrophic microorganisms assimilate
considerable amounts of carbon dioxide. Like green plastids, the predominant means by …

▪ Abstract The last decade has seen significant advances in our understanding of the
physiology, ecology, and molecular biology of chemoautotrophic bacteria. Many ecosystems …

Bacterial populations co-ordinate gene expression collectively through quorum sensing
(QS), a cell-to-cell communication mechanism employing diffusible signal molecules. The …

We describe the identification of Rex, a novel redox‐sensing repressor that appears to be
widespread among Gram‐positive bacteria. In Streptomyces coelicolor Rex binds to …

The function of the LysR‐type regulator LrhA of Escherichia coli was defined by comparing
whole‐genome mRNA profiles from wild‐type E. coli and an isogenic lrhA mutant on a DNA …

All cyanobacteria and many chemoautotrophs contain polyhedral inclusion bodies that are
bound by a unilamellar protein shell (15, 63). Isolation and enzymatic analysis of the bodies …

The nutritional versatility of facultative autotrophs requires efficient overall control of their
metabolism. Most of these organisms are Proteobacteria that assimilate CO 2 via the highly …

Few antibiotics are effective against Acinetobacter baumannii, one of the most successful
pathogens responsible for hospital-acquired infections. Resistance to chlorhexidine, an …
