Expression Analysis of the Pseudomonas aeruginosa AlgZR Two-Component Regulatory System [PDF]
ABSTRACT Pseudomonas aeruginosa virulence components are subject to complex regulatory control primarily through two-component regulatory systems that allow for sensing and responding to environmental stimuli. In this study, the expression and regulation of the P. aeruginosa AlgZR two-component

Feedback Control of Two-Component Regulatory Systems. [PDF]
Two-component systems are a dominant form of bacterial signal transduction. The prototypical two-component system consists of a sensor that responds to a specific input(s) by modifying the output of a cognate regulator. Because the output of a two-component system is the amount of phosphorylated regulator, feedback mechanisms may alter the amount of ...

Sensor domains of two-component regulatory systems. [PDF]
Two-component systems regulate crucial cellular processes in microorganisms, and each comprises a homodimeric histidine kinase receptor and a cytoplasmic response regulator. Histidine kinases, often membrane associated, detect environmental input at sensor domains and propagate resulting signals to catalytic cytoplasmic transmitter domains.

Signal integration in bacterial two-component regulatory systems. [PDF]
Two-component systems (TCSs) and phosphorelays are key mediators of bacterial signal transduction. The signals activating these systems promote the phosphorylated state of a response regulator, which is generally the form that carries out specific functions such as binding to DNA and catalysis of biochemical reactions.

The Role and Regulatory Network of the CiaRH Two-Component System in Streptococcal Species [PDF]
Pathogenic streptococcal species are responsible for a broad spectrum of human diseases ranging from non-invasive and localized infections to more aggressive and life-threatening diseases, which cause great economic losses worldwide. Streptococci possess a dozen two-component systems (TCSs) that play important roles in the response to different ...

Phosphate sink containing two-component signaling systems as tunable threshold devices [PDF]
Synthetic biology aims to design de novo biological systems and reengineer existing ones. These efforts have mostly focused on transcriptional circuits, with reengineering of signaling circuits hampered by limited understanding of their systems dynamics ...
