Regulation of toxin–antitoxin systems by proteolysis
Plasmid, 2013 Toxin-antitoxin systems are widely distributed among many bacterial species, including human pathogens. Typically, these systems consist of two genes in an operon which encodes a stable toxin disrupting essential cellular processes and a labile antitoxin preventing toxicity.

Molecular and Structural Basis of Cross-Reactivity in M. tuberculosis Toxin–Antitoxin Systems
Toxins, 2020 Mycobacterium tuberculosis genome encodes over 80 toxin–antitoxin (TA) systems. While each toxin interacts with its cognate antitoxin, the abundance of TA systems presents an opportunity for potential non-cognate interactions. TA systems mediate manifold

IUCrJ, 2022 Type II toxin–antitoxin (TA) systems encode two proteins: a toxin that inhibits cell growth and an antitoxin that neutralizes the toxin by direct intermolecular protein–protein interactions.

Association Between Toxin-Antitoxin Systems and Biofilm Formation [PDF]
Jundishapur Journal of Microbiology, 2014 Toxin-antitoxin (TA) systems are found on the chromosomes and plasmids of many Bacteria such as Escherichia coli. The roles of TA systems in bacteria are enigmatic. Multiple biological functions of TA systems are proposed including growth modulation, persistence, and biofilm formation. Biofilms of E.

The Bacillus cereus spoIIS programmed cell death system
Frontiers in Microbiology, 2015 Programmed cell death in bacteria is generally associated with two¬ component toxin antitoxin systems. The SpoIIS toxin-antitoxin system, consisting of a membrane bound SpoIISA toxin and a small, cytosolic antitoxin SpoIISB, was originally identified in ...

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.

Detection of Protein–Protein Interactions in Escherichia coli With Single Molecule Sensitivity
Advanced Science, EarlyView.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.

Minimalistic mycoplasmas harbor different functional toxin-antitoxin systems
PLOS Genetics, 2021 Mycoplasmas are minute bacteria controlled by very small genomes ranging from 0.6 to 1.4 Mbp. They encompass several important medical and veterinary pathogens that are often associated with a wide range of chronic diseases. The long persistence of mycoplasma cells in their hosts can exacerbate the spread of antimicrobial resistance observed for many ...

Asking the 5 W's for designing next‐generation bioprocessing
AIChE Journal, EarlyView.Abstract Biotechnology is expanding beyond traditional, centralized fermentation and toward next‐generation bioprocessing paradigms that emphasize flexible deployment outside the laboratory with application‐specific performance. However, many bioprocesses fail to translate beyond proof‐of‐concept into industrially viable systems because early design ...
