Taking advantage of available functional data associated with 115 transcription and 7 sigma
factors, we have performed a structural analysis of the regulatory network of Escherichia coli …

TOL plasmid pWWO of Pseudomonas putida contains two operons that specify a pathway
for the degradation of aromatic hydrocarbons. The upper pathway operon encodes the …

In this report, we experimentally demonstrate that improving the cis-regulatory region of a
target promoter can significantly enhance the response to an otherwise poor inducer. The …

Regulation of tetralin biodegradation operons is one of the examples of unconventional
LysR-type mediated transcriptional regulation. ThnR activates transcription from two …

Most bacterial promoters are regulated by several signals. This is reflected in the complexity
of their organization, with multiple binding sites for different transcription factors. Studies of a …

The bacterial hexameric helicase known as Rho is an archetypal sequence-specific
transcription terminator that typically halts the synthesis of a defined set of transcripts …

The XylR regulatory protein is a transcriptional activator from the TOL plasmid of
Pseudomonas putida mt-2 that is involved in the toluene and benzene degradation pathway …

Myxobacteria live in an ever‐changing environment and therefore require mechanisms to
couple perception of environmental change with appropriate behavioral responses. The …

The analysis of gene regulation in bacteria is entering a new phase. Global regulatory
networks, signal processing, responses of complexly regulated sets of genes, and …

In this issue, Skerker et al.(2008) present a rational method for rewiring the protein-protein
interactions and output responses of prokaryotic two-component signal transduction …
