Engineered Stable, Antibiotic‐Free, High‐Level Protein Expression in the Probiotic Chassis Escherichia coli Nissle 1917

Biotechnology and Bioengineering, EarlyView.
The probiotic E. coli Nissle 1917 was engineered to enable stable and antibiotic free protein expression platforms using native plasmids. Further modification aids in the production of high‐level protein expression for antimicrobial secretion whose activity is comparable to industry standard E. coli BL21.

RNA Regulated Toxin-Antitoxin Systems in Pathogenic Bacteria

Frontiers in Cellular and Infection Microbiology, 2021
The dynamic host environment presents a significant hurdle that pathogenic bacteria must overcome to survive and cause diseases. Consequently, these organisms have evolved molecular mechanisms to facilitate adaptation to environmental changes within the ...

Transcriptional cross-activation between toxin-antitoxin systems of Escherichia coli [PDF]

, 2013
BACKGROUND: Bacterial toxin-antitoxin (TA) systems are formed by potent regulatory or suicide factors (toxins) and their short-lived inhibitors (antitoxins). Antitoxins are DNA-binding proteins and auto-repress transcription of TA operons.

Oxidative Treatment for Reducing Persistent Populations of Escherichia coli Under Amoxicillin and Gentamicin Pressure

Journal of Biophotonics, EarlyView.
Photodynamic inactivation (PDI) with methylene blue and 660 nm LED enhances antibiotic killing of bacteria, accelerating time‐kill kinetics and reducing the MDK99 compared to antibiotics alone. SEM confirms effective cellular damage, demonstrating that PDI potentiates amoxicillin and gentamicin against tolerant bacterial populations. ABSTRACT Bacterial

TasA-tasB, a new putative toxin-antitoxin (TA) system from Bacillus thuringiensis pGI1 plasmid is a widely distributed composite mazE-doc TA system

BMC Genomics, 2006
Background Post-segregational killing systems are present in a large variety of microorganisms. When found on plasmids, they are described as addiction systems that act to maintain the plasmid during the partitioning of the cell.

Integrative Modeling in the Age of Machine Learning: A Summary of HADDOCK Strategies in CAPRI Rounds 47–55

Proteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT The HADDOCK team participated in CAPRI rounds 47–55 as server, manual predictor, and scorers. Throughout these CAPRI rounds, we used a plethora of computational strategies to predict the structure of protein complexes. Of the 10 targets comprising 24 interfaces, we achieved acceptable or better models for 3 targets in the human category and 1 ...

Toxin-Antitoxin Systems as Multilevel Interaction Systems

Toxins, 2014
Toxin-antitoxin (TA) systems are small genetic modules usually composed of a toxin and an antitoxin counteracting the activity of the toxic protein. These systems are widely spread in bacterial and archaeal genomes.
