Signal transduction: Hair brains in bacterial chemotaxis
The conserved cytoplasmic domains of bacterial chemotaxis receptors are a fibrous arrangement of alpha-helical coiled coils that look a lot like hair. Such bundles of alpha-helical filaments mediate sensory-motor responses in all prokaryotic cells. How do they work? Very nearly perfectly is probably as good an answer as any.
متن کاملAn Agent-Based Model of Signal Transduction in Bacterial Chemotaxis
We report the application of agent-based modeling to examine the signal transduction network and receptor arrays for chemotaxis in Escherichia coli, which are responsible for regulating swimming behavior in response to environmental stimuli. Agent-based modeling is a stochastic and bottom-up approach, where individual components of the modeled system are explicitly represented, and bulk propert...
متن کاملA "trimer of dimers"-based model for the chemotactic signal transduction network in bacterial chemotaxis.
The network that controls chemotaxis in Escherichia coli is one of the most completely characterized signal transduction systems to date. Receptor clustering accounts for characteristics such as high sensitivity, precise adaptation over a wide dynamic range of ligand concentrations, and robustness to variations in the amounts of intracellular proteins. To gain insights into the structure-functi...
متن کاملMind your B's and R's: bacterial chemotaxis, signal transduction and protein recognition.
The crystal structures of two key regulators of the bacterial chemotaxis pathway (CheR and CheB) have been determined. These studies add further detail to the growing picture of signal transduction and attenuation in the bacterial chemotaxis pathway. The recently determined structure of the methyltransferase CheR bound to a peptide of its target receptor, provides a structural model for intermo...
متن کاملBacterial signal transduction network in a genomic perspective.
Bacterial signalling network includes an array of numerous interacting components that monitor environmental and intracellular parameters and effect cellular response to changes in these parameters. The complexity of bacterial signalling systems makes comparative genome analysis a particularly valuable tool for their studies. Comparative studies revealed certain general trends in the organizati...
