Diversity and evolution of the vertebrate chemoreceptor gene repertoire [PDF]

Nature Communications
Chemoreception – the ability to smell and taste – is an essential sensory modality of most animals. The number and type of chemical stimuli that animals can perceive depends primarily on the diversity of chemoreceptors they possess and express.

Spatial integration of sensory input and motor output in Pseudomonas aeruginosa chemotaxis through colocalized distribution [PDF]

eLife
The 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.

Pseudomonas aeruginosa Performs Chemotaxis to All Major Human Neurotransmitters [PDF]

Microbial Biotechnology
The ubiquitous pathogen Pseudomonas aeruginosa is attracted to γ‐aminobutyrate (GABA), acetylcholine, histamine, serotonin, epinephrine, norepinephrine, dopamine, tyramine, glycine, and glutamate via chemotaxis.

Phospho-mimetic CheV interacts with a subset of chemoreceptors [PDF]

mBio
Chemotaxis 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 the Neurotransmitters Serotonin, Dopamine, Epinephrine and Norepinephrine [PDF]

Microbial Biotechnology
Bacteria 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

HilD-regulated chemotaxis proteins contribute to Salmonella Typhimurium colonization in the gut [PDF]

mBio
In the enteric pathogen Salmonella Typhimurium, invasion and motility are coordinated by HilD, a master regulator that activates expression of genes encoding the type III secretion system 1 and some motility genes, including the chemotaxis gene mcpC ...

A Two‐Protein Chemoreceptor Complex Regulates Oxygen Thresholds in Bacterial Magneto‐Aerotaxis [PDF]

Advanced Science
Bacteria in changing environments rely on motility and sensory mechanisms to locate optimal conditions. This process depends on specialized chemoreceptors to sense environmental stimuli.

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.
