MetabolomicsThe pyruvate kinase, a metabolic sensor powering glycolysis, drives the metabolic control of DNA replication

BACKGROUND: In all living organisms, DNA replication is exquisitely regulated in a wide range of growth conditions to achieve timely and accurate genome duplication prior to cell division. Failures in this regulation cause DNA damage with potentially disastrous consequences ...

MetabolomicsCombined transcriptome and metabolome analysis reveals the regulatory network of histidine kinase QseC in the two-component system of Glaesserella parasuis
Glaesserella parasuis is the causative agent of Glässer's disease in pigs, which can lead to polyserositis, arthritis, and meningitis. This study used transcriptome and metabolomics sequencing techniques to investigate the mechanism of action of qseC gene in Glaesserella parasuis. Transmission elect...

TranscriptomicsThe cell envelope stress response mediated by the LiaFSRLm three-component system of Listeria monocytogenes is controlled via the phosphatase activity of the bifunctional histidine kinase LiaSLm
Most members of the phylum Firmicutes harbor a two-component system, LiaSR, which is involved in the response to cell envelope stress elicited most notably by inhibitors of the lipid II cycle. In all LiaSR systems studied in detail LiaSR-mediated signal transduction was shown to be negatively contro...

Transcriptomicsdelta-arcS versus wild-type
The availability of oxygen is a major environmental factor for many microbes, in particular for bacteria, such as Shewanella species, which thrive in redox-stratified environments. One of the best studied systems involved in mediating the response to changes in environmental oxygen levels is the Arc...

TranscriptomicsA novel hybrid kinase is essential for regulating the σB-mediated stress response of Bacillus cereus.
A common bacterial strategy for monitoring environmental challenges is to use two-component systems, which consist of a sensor histidine kinase (HK) and a response regulator (RR). In the food-borne pathogen Bacillus cereus, the alternative sigma factor σB is activated by the RR RsbY. Here we presen...

TranscriptomicsConserved nutrient sensor O-GlcNAc transferase is integral to the C. elegans pathogen-specific immune response
Discriminating pathogenic bacteria from energy-harvesting commensals is key to host immunity. Using mutants defective in the enzymes of O-linked N-acetylglucosamine (O-GlcNAc) cycling, we examined the role of this nutrient-sensing pathway in the Caenorhabidits elegans innate immune response. Using w...

TranscriptomicsTranscription analysis of the sensor kinase PA4398 in Pseudomonas aeruginosa PA14 under swarming conditions.
In this experiment the transcriptional profile of the Pseudomonas aeruginosa PA14 two-component sensor kinase PA4398 was investigated under swarming conditions using DNA microarrays. To this aim three independent cultures of the PA14 wild-type and the PA4398 mutant were grown until mid-log phase in ...

ProteomicsPSKH1 kinase activity is differentially modulated via allosteric binding of Ca2+ sensor proteins
Protein Serine Kinase H1 (PSKH1) was recently identified as a crucial factor in kidney development and is overexpressed in prostate, lung and kidney cancers. However, little is known about PSKH1’s regulation, leading to its classification as a “dark” kinase. Here, we used biochemistry and mass spect...

TranscriptomicsRegulation of sialidase production in clostridium perfringens by the orphan sensor histidine kinase ReeS
ReeS, previously named as CPE1512, was originally annotated as the only hybrid sensor histidine kinase/response regulator in Clostridium perfringens. Further evidence suggests that ReeS is more likely to function as an orphan sensor histidine kinase. A reeS deletion mutant was constructed and the tr...
