Divalent Cation Signaling in Clostridium perfringens Spore Germination

Microorganisms, 2023
Spore germination plays an essential role in the pathogenesis of Clostridium perfringens-associated food poisoning. Germination is initiated when bacterial spores sense various stimuli, including chemicals and enzymes.

Synthesis and characterization of divalent ion conductors with NASICON-type structures

Journal of Asian Ceramic Societies, 2019
Divalent ion-conducting solid electrolytes with NASICON-type three-dimensional network structures (MxHf1−x)4/(4−2x)Nb(PO4)3 (M = Ni, Mg, Ca, Sr) were successfully developed by introducing M2+ cations into HfNb(PO4)3 solids.

Translational Entropy-Driven Competitive and Additive Effects on DNA Higher-Order Structure via Ion Exchange Between Cations of Different Valencies

Entropy
DNA conformational transitions in aqueous environments are strongly influenced by electrostatic interactions with surrounding cations. This review/perspective article summarizes the experimental findings reported during the last decade on the competitive/

Acidic pH and divalent cation sensing by PhoQ are dispensable for systemic salmonellae virulence

eLife, 2015
Salmonella PhoQ is a histidine kinase with a periplasmic sensor domain (PD) that promotes virulence by detecting the macrophage phagosome. PhoQ activity is repressed by divalent cations and induced in environments of acidic pH, limited divalent cations ...

The structural basis of divalent cation block in a tetrameric prokaryotic sodium channel

Nature Communications, 2023
Divalent cation block is observed in various tetrameric ion channels. For blocking, a divalent cation is thought to bind in the ion pathway of the channel, but such block has not yet been directly observed.

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

FEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...
