    Rewiring the Specificity of Two-Component Signal Transduction Systems Jeffrey M. Skerker,1,4 Barrett S. Perchuk,1 Albert Siryaporn,2 Emma A.

Laub1,* 1Department of Biology, Massachusetts Institute of Technology, Cambridge, MA , USA 2Department of Physics 3Department of Biology University of Pennsylvania, Philadelphia, PA , .   The two-component system (TCS) 1 is the signal transduction pathway widely employed from prokaryotes to eukaryotes. Typically, TCS is composed of a sensor that monitors an external signal(s) and a response regulator that controls gene expression or other physiological activities such as chemotaxis ().In bacteria, TCS is the major system of signal transduction but not in Archaea and .

      BASIC PLAYERS: IT TAKES TWO TO SIGNAL. The basic two-component system involves a sensor kinase, or HPK, as well as an RR. As depicted in Figure1, the role of the HPK is to direct phosphorylation of its cognate RR in response to a specific environmental signal; this phosphorylation regulates the activity of the bacteria make extensive use of such systems. ArsRS two-component signal transduction system has an im-portant role in allowing H. pylori to sense and regulate target genes in response to changes in pH and is required for colo-nization of the stomach (25, 29, 31–33, 50, 51). This two-component system is comprised of a sensor kinase (ArsS, cor-responding to HP in H. pylori ) and Cited by:

Bacteria often employ tens or hundreds of these paralogous signaling systems, comprised of histidine kinases (HKs) and their cognate response regulators (RRs).

Some bacteria can contain as many as two-component systems that need tight regulation to prevent unwanted cross-talk. The two-component system is a broad signal transduction pathway in bacteria.

It plays a major role in adapting to changing environmental conditions such as cell envelope stress response, phosphate. The archetypal two-component signal transduction systems include a sensor module, which consists of an extracytoplasmic or membrane-associated sensor input domain and a cytoplasmic histidine kinase domain with an ATPase and phosphoacceptor subdomains, and a response regulator, which consists of a receiver CheY-like domain and a DNA-binding domain.

Most prokaryotic signal-transduction systems and a few eukaryotic pathways use phosphotransfer schemes involving two conserved components, a histidine protein kinase and a response regulator by:   Fig. 1.—Schematic diagram illustrating phosphorelay in two-component signal transduction systems.

In a new chapter, an introduction to signal transduction, the book provides a concise overview of receptor mechanisms, from receptor – ligand interactions to post-translational modifications operational in the. Two-component systems (TCSs) are common signal transduction pathways found abundantly in most phyla except animals.

The basic TCS pathway involves two multi-domain proteins. The first is a histidine protein kinase (HPK) whose autokinase activity is dependent upon an environmental stimulus.

To exist in a wide range of environmental niches, bacteria must sense and respond to a variety of external signals. A primary means by which this occurs is through two-component signal transduction pathways, typically composed of a sensor histidine kinase that receives the input stimuli and then phosphorylates a response regulator that effects an appropriate change in cellular physiology Cited by: ComDE Two-component Signal Transduction Systems in Oral Streptococci: Structure and Function Yue Zu, Wei Li, Qi Wang, Jiahao Chen and Qiang Guo.

Oral streptococci depend on two-component signal transduction systems (TCSs), the most widespread regulatory systems in bacteria, to detect and respond to diverse stresses in oral environment.

Two-component systems are involved in various signal transduction pathways in many prokaryotes, fungi, slime molds, and plants (Stock et al., ).The prototypical two-component system is a major signaling mechanism that mediates the response to various environmental stimuli in bacteria.
