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]

open access: yesMicroorganisms
Bacterial 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]

open access: yesmBio
Toxin: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.

Protein expression, crystallization and preliminary X-ray crystallographic analysis of the isolatedShigella flexneriVapC toxin [PDF]

open access: greenActa Crystallographica Section F Structural Biology and Crystallization Communications, 2013
Upon release from the stable complex formed with its antitoxin VapB, the toxin VapC (MvpT) of the Gram-negative pathogen Shigella flexneri is capable of globally down-regulating translation by specifically cleaving initiator tRNA(fMet) in the anticodon region.

Regulation of Enteric vapBC Transcription: Induction by VapC Toxin Dimer-Breaking

open access: goldNucleic Acids Research, 2012
Toxin-antitoxin (TA) loci encode inhibitors of translation, replication or cell wall synthesis and are common elements of prokaryotic plasmids and chromosomes. Ten TA loci of Escherichia coli K-12 encode mRNases that cumulatively contribute to persistence (multidrug tolerance) of the bacterial cells. The mechanisms underlying induction and reversion of

Apoptosis like symptoms associated with abortive infection of Mycobacterium smegmatis by mycobacteriophage D29. [PDF]

open access: yesPLoS ONE, 2022
Mycobacteriophages are phages that infect mycobacteria resulting in their killing. Although lysis is the primary mechanism by which mycobacteriophages cause cell death, others such as abortive infection may also be involved.

Generation of a toxin/antitoxin-based counterselection marker for Chlamydia trachomatis [PDF]

open access: yesInfection and Immunity
Chlamydia trachomatis is the leading cause of bacterial sexually transmitted infection in the United States. The high rate of asymptomatic cases and absence of a vaccine often leave infections untreated, increasing the risk of serious complications in ...
