▪ Abstract The promoter recognition specificity of Escherichia coli RNA polymerase is
modulated by replacement of the σ subunit in the first step and by interaction with …

Proteomics has emerged as an indispensable methodology for large-scale protein analysis
in functional genomics. The Escherichia coli proteome has been extensively studied and is …

The σS (or RpoS) subunit of RNA polymerase is the master regulator of the general stress
response in Escherichia coli. While nearly absent in rapidly growing cells, σS is strongly …

When conditions cause bacterial growth to stop, extensive reprogramming of physiology and
gene expression allows for the cell's survival. We used whole‐genome DNA arrays to …

The σS subunit of RNA polymerase, the product of the rpoS gene, controls the expression of
genes responding to starvation and cellular stresses. Using gene array technology, we …

The global transcriptional regulator H-NS selectively silences bacterial genes associated
with pathogenicity and responses to environmental insults. Although there is ample …

Little is known about the molecular mechanism by which histone-like nucleoid-structuring (H-
NS) protein and cyclic AMP-catabolite activator protein (CAP) complex control bacterial …

Bacillus subtilis displays a complex adaptive response to the presence of reactive oxygen
species. To date, most proteins that protect against reactive oxygen species are members of …

In several Gram-positive and Gram-negative bacteria glutamate decarboxylases play an
important role in the maintenance of cellular homeostasis in acid environments. Here, new …

Many bacterial species exhibit a general stress response that can be induced by numerous
very different stress conditions and, phenotypically, renders the cells broadly stress resistant …
