Histidine residue 94 is involved in pH sensing by histidine kinase ArsS of Helicobacter pylori. [PDF]

PLoS ONE, 2009
The ArsRS two-component system is the master regulator of acid adaptation in the human gastric pathogen Helicobacter pylori. Low pH is supposed to trigger the autophosphorylation of the histidine kinase ArsS and the subsequent transfer of the phosphoryl ...

The PAS domain-containing histidine kinase RpfS is a second sensor for the diffusible signal factor of Xanthomonas campestris [PDF]

, 2014
Summary: A cell-cell signalling system mediated by the fatty acid signal DSF controls the virulence of Xanthomonas campestris pv. campestris (Xcc) to plants. The synthesis and recognition of the DSF signal depends upon different Rpf proteins.

Comparative analysis of two paradigm bacteriophytochromes reveals opposite functionalities in two-component signaling

Nature Communications, 2021
The bacteriophytochrome DrBphP from Deinococcus radiodurans shows high sequence homology to the histidine kinase Agp1 from Agrobacterium fabrum but lacks kinase activity.

Nitric Oxide Mediates Biofilm Formation and Symbiosis in Silicibacter sp. Strain TrichCH4B. [PDF]

, 2015
UnlabelledNitric oxide (NO) plays an important signaling role in all domains of life. Many bacteria contain a heme-nitric oxide/oxygen binding (H-NOX) protein that selectively binds NO.

Phenylpyrrole fungicides act on triosephosphate isomerase to induce methylglyoxal stress and alter hybrid histidine kinase activity

Scientific Reports, 2019
Fludioxonil, a natural product of pyrrolnitrin, is a potent fungicide used on crops worldwide. Drug action requires the presence of a group III hybrid histidine kinase (HHK) and the high osmolarity glycerol (HOG) pathway.

Oligomeric states in sodium ion-dependent regulation of cyanobacterial histidine kinase-2 [PDF]

, 2017
Two-component signal transduction systems (TCSs) consist of sensor histidine kinases and response regulators. TCSs mediate adaptation to environmental changes in bacteria, plants, fungi and protists. Histidine kinase 2 (Hik2) is a sensor histidine kinase

How Can a Histidine Kinase Respond to Mechanical Stress?

Frontiers in Microbiology, 2021
Bacteria respond to physical forces perceived as mechanical stress as part of their comprehensive environmental sensing strategy. Histidine kinases can then funnel diverse environmental stimuli into changes in gene expression through a series of ...

Hybrid histidine kinase activation by cyclic di-GMP–mediated domain liberation

Proceedings of the National Academy of Sciences of the United States of America, 2019
Significance Expression of bacterial genes in response to various cues is predominantly regulated by 2- or multicomponent systems with autophosphorylation of a histidine kinase (HK), the first component, being controlled by an N-terminal sensor domain ...

β-Catenin is a pH sensor with decreased stability at higher intracellular pH. [PDF]

, 2018
β-Catenin functions as an adherens junction protein for cell-cell adhesion and as a signaling protein. β-catenin function is dependent on its stability, which is regulated by protein-protein interactions that stabilize β-catenin or target it for ...
