Bacteria have evolved many different signal transduction systems that sense signals and
generate a variety of responses. Generally, most abundant are transcriptional regulators …

Interspecies electron transfer is a key process in methanogenic and sulphate-reducing
environments. Bacteria and archaea that live in syntrophic communities take advantage of …

SUMMARY PAS domains are newly recognized signaling domains that are widely
distributed in proteins from members of the Archaea and Bacteria and from fungi, plants …

Pathogens that infect the gastrointestinal and respiratory tracts are subjected to intense
pressure due to the environmental conditions of the surroundings. This pressure has led to …

Per-Arnt-Sim (PAS) domains occur in proteins from all kingdoms of life. In the bacterial
kingdom, PAS domains are commonly positioned at the amino terminus of signaling proteins …

In many organisms, metabolite interconversion at the phosphoenolpyruvate (PEP)–pyruvate–
oxaloacetate node involves a structurally entangled set of reactions that interconnects the …

The genus Salmonella contains two species, S. bongori and S. enterica. Compared to the
well-studied S. enterica there is a marked lack of information regarding the genetic makeup …

Signal transduction in microorganisms and plants is often mediated by His–Asp
phosphorelay systems. Two conserved families of proteins are centrally involved: histidine …

We report here the sequencing and analysis of the genome of the nitrogen-fixing endophyte,
Klebsiella pneumoniae 342. Although K. pneumoniae 342 is a member of the enteric …

In developing countries, it still suffers from endless problems regarding wastewater
treatment and the problem of choosing the appropriate treatment system due to lack of …
