Interplay between Two-Component Regulatory Systems Is Involved in Control of Cupriavidus metallidurans Metal Resistance Genes. [PDF]
Metal resistance of Cupriavidus metallidurans is based on determinants that were acquired in the past by horizontal gene transfer during evolution. Some of these determinants encode transmembrane metal efflux systems. Expression of most of the respective

A Radical Reimagining of Fungal Two-Component Regulatory Systems. [PDF]
Bacterial two-component regulatory systems (TCSs) mediate signal transduction by transferring phosphoryl groups between sensor kinase and response regulator proteins, sometimes using intermediary histidine-phosphotransferase (Hpt) domains to form multistep phosphorelays.

Roles of two-component regulatory systems in antibiotic resistance. [PDF]
Two-component regulatory systems (TCSs) are a major mechanism by which bacteria sense and respond to changes in their environment. TCSs typically consist of two proteins that bring about major regulation of the cell genome through coordinated action mediated by phosphorylation.

Two Component Regulatory Systems and Antibiotic Resistance in Gram-Negative Pathogens. [PDF]
Gram-negative pathogens such as Klebsiella pneumoniae, Acinetobacter baumannii, and Pseudomonas aeruginosa are the leading cause of nosocomial infections throughout the world. One commonality shared among these pathogens is their ubiquitous presence, robust host-colonization and most importantly, resistance to antibiotics.

Regulatory dynamics of standard two-component systems in bacteria [PDF]
Here, we study 14 two-component systems in Escherichia coli, which have been experimentally characterized with respect to their transcriptional regulation and their perceived signal. Given that the activity of these sensory units is connected to the rest of the transcriptional network, we first classify them as autonomous, semiautonomous or dependent ...

Drug inhibition of bacterial two-component regulatory systems
There are several ways to adapt and increase the chances of survival of microorganisms. Specific systems involved in the recognition of external changes and the organization of the corresponding reaction of the microorganism are called bacterial sensory ...

Autoamplification of a Two-Component Regulatory System Results in “Learning” Behavior [PDF]
ABSTRACT We have tested the hypothesis that the autoamplification of two-component regulatory systems results in “learning” behavior, i.e., that bacteria respond faster or more extensively to a signal when a similar signal has been perceived in the past.

Protein phosphorylation in chemotaxis and two-component regulatory systems of bacteria [PDF]
Two-component regulatory systems appear to be widespread in bacteria. Phosphorylation has been demonstrated in three of the known systems and correlated with in vivo function in two cases (Che and Ntr). Although phosphorylation of sensor and regulator proteins has so far been observed exclusively in vitro, transient protein phosphorylation could ...

A comprehensive analysis of pneumococcal two-component system regulatory networks [PDF]
Abstract Two-component systems are key signal-transduction systems that enable bacteria to respond to a wide variety of environmental stimuli. The human pathogen, Streptococcus pneumoniae (pneumococcus) encodes 13 two-component systems and a single orphan response regulator, most of which are significant for pneumococcal pathogenicity ...
