The Helicobacter pylori TlpD cytoplasmic chemoreceptor requires an intact C-terminus for polar localization and function [PDF]
Journal of BacteriologyBacteria localize proteins to distinct subcellular locations, including chemoreceptors, which frequently localize to the bacterial pole. Although some polarity-promoting mechanisms have been described, many chemoreceptors lack clear routes to becoming ...

Spatial integration of sensory input and motor output in Pseudomonas aeruginosa chemotaxis through colocalized distribution [PDF]
eLifeThe opportunistic pathogen Pseudomonas aeruginosa serves as a model organism for studying multiple signal transduction pathways. The chemoreceptor cluster, a core component of the chemotaxis pathway, is assembled from hundreds of proteins.

Agrobacterium fabrum (tumefaciens) Chemosensory System: A Typical Model of One Histidine Kinase for Two Coupling Proteins and Multiple Response Regulators [PDF]
MicroorganismsBacteria utilize chemotaxis to sense the surrounding chemical signals to seek a more favorable survival environment. The chemotaxis process includes signal sensing, signal transduction, and signal response (i.e., regulating flagellar rotation to control ...

Phospho-mimetic CheV interacts with a subset of chemoreceptors [PDF]
mBioChemotaxis pathways are among the most complex signaling systems in bacteria. A central feature of these pathways is the ternary complex formed by chemoreceptors, the autokinase CheA, and the coupling proteins CheW and CheV.

Pseudomonas aeruginosa Performs Chemotaxis to All Major Human Neurotransmitters [PDF]
Microbial BiotechnologyThe ubiquitous pathogen Pseudomonas aeruginosa is attracted to γ‐aminobutyrate (GABA), acetylcholine, histamine, serotonin, epinephrine, norepinephrine, dopamine, tyramine, glycine, and glutamate via chemotaxis.

Pseudomonas aeruginosa Performs Chemotaxis to the Neurotransmitters Serotonin, Dopamine, Epinephrine and Norepinephrine [PDF]
Microbial BiotechnologyBacteria use chemotaxis to move to favourable ecological niches. For many pathogenic bacteria, chemotaxis is required for full virulence, particularly for the initiation of host colonisation. There do not appear to be limits to the type of compounds that

The role of membrane-mediated interactions in the assembly and architecture of chemoreceptor lattices. [PDF]
PLoS Computational Biology, 2014 In vivo fluorescence microscopy and electron cryo-tomography have revealed that chemoreceptors self-assemble into extended honeycomb lattices of chemoreceptor trimers with a well-defined relative orientation of trimers.

Plasticity of the chemoreceptor repertoire in Drosophila melanogaster. [PDF]
PLoS Genetics, 2009 For most organisms, chemosensation is critical for survival and is mediated by large families of chemoreceptor proteins, whose expression must be tuned appropriately to changes in the chemical environment.

Opposing chemosensory functions of closely related gustatory receptors
eLife, 2023 In the fruit fly Drosophila melanogaster, gustatory sensory neurons express taste receptors that are tuned to distinct groups of chemicals, thereby activating neural ensembles that elicit either feeding or avoidance behavior.
