Detection of Protein–Protein Interactions in Escherichia coli With Single Molecule Sensitivity

Advanced Science, Volume 13, Issue 37, 3 July 2026.
This article describes a regulatory circuit in Escherichia coli able to detect protein–protein interactions with exquisite sensitivity. The interaction between two hybrid proteins fused to Bordetella pertussis adenylate cyclase and its activator calmodulin triggers a potent cyclic AMP signaling cascade.

Decoding Viral Dark Matter: Metagenomic Prokaryotic Virus Characterization With Pharokka, Phold, and Phynteny

Current Protocols, Volume 6, Issue 7, July 2026.
Abstract Viral metagenomics is an increasingly powerful tool for understanding the function and structure of viruses across the diverse environments of our planet. However, decoding the functional potential of prokaryotic viral metagenomes is extremely challenging.

A competence-regulated toxin-antitoxin system in Haemophilus influenzae.

PLoS ONE, 2020
Natural competence allows bacteria to respond to environmental and nutritional cues by taking up free DNA from their surroundings, thus gaining both nutrients and genetic information.

A differential effect of E. coli toxin-antitoxin systems on cell death in liquid media and biofilm formation. [PDF]

PLoS ONE, 2009
Toxin-antitoxin (TA) modules are gene pairs specifying for a toxin and its antitoxin and are found on the chromosomes of many bacteria including pathogens. Here we report how each of five such TA systems in E. coli affect bacterial cell death differently

Multi‐Induction Strategies in Crops: Mechanisms, Synergistic Effects, and Sustainable Applications for Enhanced Secondary Metabolite Production

Food Frontiers, Volume 7, Issue 4, July 2026.
This review analyzes single/combined abiotic (light, water, nutrients, hormones) and biotic (microbes, yeast) elicitors regulating signaling, gene expression, and metabolism to boost plant secondary metabolites. It highlights synergistic multielicitor strategies for crop quality and functional foods, while critically addressing current limitations and ...

Bioinformatics‐Driven Design and Evaluation of Recombinant Multi‐Epitope Immunogens Derived From Snake Venom Toxins as Potential Antivenom Candidates

Proteins: Structure, Function, and Bioinformatics, Volume 94, Issue 7, Page 1403-1426, July 2026.
ABSTRACT Snakebite envenomation is a major public health concern, particularly in low‐ and middle‐income regions where access to safe and effective antivenoms is limited. Traditional antivenoms, derived from immunization with crude venom, often trigger adverse reactions and lack specificity against key venom components.

Genetic Toolbox Expansion Enables Constitutively Fluorescent Lacticaseibacillus rhamnosus for Functional Microbiome Research

Microbial Biotechnology, Volume 19, Issue 7, July 2026.
We expanded the genetic toolkit for Lacticaseibacillus rhamnosus by enabling direct cloning, and leveraging five constitutive promoters and a repressor system. Fluorescent L. rhamnosus strains with different fluorochromes engineered with the high‐performing PtlpA promoter demonstrated functionality in microbial competition assays, supporting microbiome

Keeping the wolves at bay: antitoxins of prokaryotic type II toxin-antitoxin systems

Frontiers in Molecular Biosciences, 2016
In their initial stages of discovery, prokaryotic toxin-antitoxin (TA) systems were confined to bacterial plasmids where they function to mediate the maintenance and stability of usually low- to medium-copy number plasmids through the post-segregational ...
