Bacterial 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 کاملInformation processing in bacterial chemotaxis.
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" t...
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 کاملInformation and Metabolism in Bacterial Chemotaxis
One of the most important issues in theoretical biology is to understand how control mechanisms are deployed by organisms to maintain their homeostasis and ensure their survival. A crucial issue is how organisms deal with environmental information in a way that ensures appropriate exchanges with the environment—even in the most basic of life forms (namely, bacteria). In this paper, I present an...
