Information processing in bacterial chemotaxis.
نویسندگان
چکیده
Motile bacteria respond to attractants and repellents in their environment by changing their movement. Stock et al. describe the similarities of the bacterial chemotaxis signaling system to eukaryotic signaling cascades. Also included is a discussion of how the ordered signaling complex of the receptor, the kinase CheA, and the kinase regulator CheW can be thought of as a primitive "probrain" to allow the integration of signals to produce the optimal cellular response.

M otile bacteria move with purpose: their movement machinery, whether for swimming or gliding, is responsive to environmental cues and enables them to seek optimal living habitats. The best studied of these bacterial behaviors is chemotaxis, the movement of an organism toward or away from particular chemicals. Although first described in the late 1800s, scientists resumed studying chemotaxis in...
متن کاملMolecular information processing: lessons from bacterial chemotaxis.
Extracellular information is converted into a usable intracellular form via signal transduction. This critically important process occurs in both unicellular and multicellular organisms throughout the living world and is exhibited by prokaryotic and eukaryotic cells alike. The mechanistic details of information processing in living cells vary from case to case, but diverse systems nevertheless ...
متن کاملBacterial chemotaxis: information processing, thermodynamics, and behavior.
Escherichia coli has long been used as a model organism due to the extensive experimental characterization of its pathways and molecular components. Take chemotaxis as an example, which allows bacteria to sense and swim in response to chemicals, such as nutrients and toxins. Many of the pathway's remarkable sensing and signaling properties are now concisely summarized in terms of design (or eng...
متن کاملResponse regulator output in bacterial chemotaxis.
Chemotaxis responses in Escherichia coli are mediated by the phosphorylated response-regulator protein P-CheY. Biochemical and genetic studies have established the mechanisms by which the various components of the chemotaxis system, the membrane receptors and Che proteins function to modulate levels of CheY phosphorylation. Detailed models have been formulated to explain chemotaxis sensing in q...
