Toxin–Antitoxin Systems in Bacillus subtilis

open access: yesToxins, 2019
Toxin−antitoxin (TA) systems were originally discovered as plasmid maintenance systems in a multitude of free-living bacteria, but were afterwards found to also be widespread in bacterial chromosomes.

A toxin-antitoxin module in Bacillus subtilis can both mitigate and amplify effects of lethal stress. [PDF]

open access: yesPLoS ONE, 2011
Bacterial type-2 (protein-protein) toxin-antitoxin (TA) modules are two-gene operons that are thought to participate in the response to stress. Previous work with Escherichia coli has led to a debate in which some investigators conclude that the modules ...

Defense Systems and Prophage Detection in Streptococcus mutans Strains

open access: yesMolecular Oral Microbiology, EarlyView.
ABSTRACT Although the species is extensively studied, limited data are available on antiphage defense systems (APDSs) in Streptococcus mutans. The present study aimed to explore the diversity and the occurrence of APDSs and to search for prophages in the genomes of clinical isolates of S. mutans using bioinformatics tools.

A Type III protein-RNA toxin-antitoxin system from Bacillus thuringiensis promotes plasmid retention during spore development. [PDF]

open access: yes, 2015
Members of the Bacillus cereus sensu lato group of bacteria often contain multiple large plasmids, including those encoding virulence factors in B. anthracis. Bacillus species can develop into spores in response to stress.

Expanded Functional Characterization and Optimization of Protein Expression in Treponema denticola Shuttle Plasmids

open access: yesMolecular Oral Microbiology, EarlyView.
We report optimization of the Treponema denticola shuttle plasmid system by minimizing its size and by characterizing an array of promoter‐gene constructs for genetic complementation, including the first use in Treponema of a Tet‐inducible system for controlled expression of potentially toxic genes.

Viable but Nonculturable State, a Survival Strategy for Salmonella in Aquatic Environments

open access: yesWater and Environment Journal, EarlyView.
Transition of Salmonella from a culturable state to a viable but nonculturable state under various environmental stresses and current methods for detecting viable Salmonella in environmental samples. ABSTRACT In the relentless battle for survival, Salmonella has evolved mechanisms to withstand harsh conditions such as extreme temperatures, fluctuating ...

Protein design and RNA design: Perspectives

open access: yesQuantitative Biology, Volume 14, Issue 2, June 2026.
Abstract Advances in deep learning and generative modeling have transformed the landscape of protein and RNA design, enabling rapid and precise creation of novel biomolecules with tailored structures and functions. In protein design, generative deep learning frameworks now support backbone generation, sequence optimization, and joint sequence–structure

Resonant activation: a strategy against bacterial persistence

open access: yes, 2010
A bacterial colony may develop a small number of cells genetically identical to, but phenotypically different from other normally growing bacteria. These so-called persister cells keep themselves in a dormant state and thus are insensitive to antibiotic ...
