Complexity in ‘2-component’ signal transduction systems
The prototypical (Class I) sensory histidine kinase is comprised of a ligand binding domain coupled to an autokinase domain (Figure 1A). Ligand binding causes activation of the catalytic autokinase domain which hydrolyses ATP and autophosphorylates a conserved histidine residue located in a sub-domain of the histidine kinase. Transfer of this high energy phosphoryl group to a conserved aspartat...
متن کاملTwo-component systems in plant signal transduction.
In plants, two-component systems play important roles in signal transduction in response to environmental stimuli and growth regulators. Genetic and biochemical analyses indicate that sensory hybrid-type histidine kinases, ETR1 and its homologs, function as ethylene receptors and negative regulators in ethylene signaling. Two other hybrid-type histidine kinases, CKI1 and ATHK1, are implicated i...
متن کاملTwo-component signal transduction.
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 protein. The histidine protein kinase, which is regulated by environmental stimuli, autophosphorylates at a histidine residue, creating a high-energy phosphoryl group that is subsequently transferred to an ...
متن کاملTwo-component signal transduction systems in oral bacteria
We present an overview of how members of the oral microbiota respond to their environment by regulating gene expression through two-component signal transduction systems (TCSs) to support conditions compatible with homeostasis in oral biofilms or drive the equilibrium toward dysbiosis in response to environmental changes. Using studies on the sub-gingival Gram-negative anaerobe Porphyromonas gi...
متن کاملOne-component systems dominate signal transduction in prokaryotes.
Two-component systems that link environmental signals to cellular responses are viewed as the primary mode of signal transduction in prokaryotes. By analyzing information encoded by 145 prokaryotic genomes, we found that the majority of signal transduction systems consist of a single protein that contains input and output domains but lacks phosphotransfer domains typical of two-component system...
