(2012-11-20)Methyl-accepting chemotaxis proteins MCPs can bind one or more receptor- specific ligands. In the case of the Tar MCP of Escherichia coli (TarEc), a primary attractant ligand is aspartate. Its binding to the periplasmic ...

(2013-02-04)Cellular movement in response to a chemical gradient, known as chemotaxis, is a critical behavior in many developmental and pathological processes such as embryo development and cancer metastasis. This cell movement can ...
-
(2017-12-11)The co-existence of ~1014 commensal bacteria and host cells in the human gastrointestinal (GI) tract creates an environment rich in molecules produced by both. The close-proximity of different signals and cells in the GI ...
-
(2017-05-08)Bacteria navigate within their environment in response to gradients of several environmental cues, including nutrients, toxins, pH, temperature and oxygen. Recent studies demonstrate that Escherichia coli also senses ...

(Texas A&M University, 2006-10-30)Membrane-bound receptors transmit information from the cell exterior to the cell interior. Bacterial receptors capable of transmitting this information include sensor kinases, which control gene expression via response ...

(2015-09-25)3,4-Dihydroxymandelic Acid (DHMA) has been reported to attract Escherichia coli by binding to the serine-binding sites of the bacteria’s Tsr chemoreceptor. Signaling via the Tsr chemoreceptor may promote the growth and ...
-
(2021-08-31)Bacterial chemotaxis to microbial-derived metabolites likely plays a key role in shaping the diversity in microbial communities in the gastrointestinal tract (GI tract). Among the important metabolites is indole, which ...

(2022-11-14)Bacteria are amongst the most resilient living organisms that rapidly and robustly adapt to different types of environments. Their remarkable success in colonizing almost all parts of the planet is aided in part by their ...
-
(2022-04-04)All major processes in living systems depend on energy sources. In bacteria undergoing cellular respiration, the central source of energy is the proton motive force (PMF). In addition to ATP synthesis, the PMF directly ...

(Texas A&M University, 2006-08-16)The transmembrane serine receptor Tsr associates with a coupling protein, CheW, and a histidine kinase, CheA, to form a ternary complex that regulates the activity of CheA. CheA activity is inhibited by binding of L-serine ...
