The Benefits of Toxicity: M. smegmatis VapBC TA Module Is Induced by Tetracycline Exposure and Promotes Survival [PDF]
Microorganisms, 2023 Toxin–antitoxin (TA) systems are widely present in bacterial genomes. Mycolicibacterium smegmatis, a common model organism for studying Mycobacterium tuberculosis physiology, has eight TA loci, including mazEF and vapBC.

The Toxin of VapBC-1 Toxin-Antitoxin Module from Leptospira interrogans Is a Ribonuclease That Does Not Arrest Bacterial Growth but Affects Cell Viability [PDF]
MicroorganismsBacterial ubiquitous Toxin-Antitoxin (TA) systems are considered to be important survival mechanisms during stress conditions. In regular environmental conditions, the antitoxin blocks the toxin, whereas during imbalanced conditions, the antitoxin ...

Shared mechanisms of enhanced plasmid maintenance and antibiotic tolerance mediated by the VapBC toxin:antitoxin system [PDF]
mBioToxin:antitoxin (TA) systems are widespread in bacteria and were first identified as plasmid addiction systems that kill bacteria lacking a TA-encoding plasmid following cell division.

Toxin-antitoxin loci
BMC Microbiology, 2012 Background Nontypeable Haemophilus influenzae (NTHi) is a significant human pathogen responsible for respiratory tract infections and the most common cause of recurrent otitis media. Type II toxin-antitoxin (TA) systems are genetic elements that code for

Interplay between transcriptional regulators and VapBC toxin-antitoxin loci during thermal stress response in extremely thermoacidophilic archaea. [PDF]
Environ Microbiol, 2023 Thermoacidophilic archaea lack sigma factors and the large inventory of heat shock proteins (HSP) widespread in bacterial genomes, suggesting other strategies for handling thermal stress are involved.

tRNAfMet Inactivating Mycobacterium tuberculosis VapBC Toxin-Antitoxin Systems as Therapeutic Targets. [PDF]
Antimicrob Agents Chemother, 2022 The Mycobacterium tuberculosis genome contains an abundance of toxin-antitoxin (TA) systems, 50 of which belong to the VapBC family. The activity of VapC toxins is controlled by dynamic association with their cognate antitoxins—the toxin is inactive when
