Phosphorylation of VapB antitoxins affects intermolecular interactions to regulate VapC toxin activity in Mycobacterium tuberculosis. [PDF]
ABSTRACT Toxin–antitoxin modules are present in many bacterial pathogens. The VapBC family is particularly abundant in members of the Mycobacterium tuberculosis complex, with 50 modules present in the M. tuberculosis genome.

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

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

Understanding the physiological role and cross-interaction network of VapBC35 toxin-antitoxin system from Mycobacterium tuberculosis [PDF]
The VapBC toxin-antitoxin (TA) system, composed of VapC toxin and VapB antitoxin, has gained attention due to its relative abundance in members of the M. tuberculosis complex.

The N-terminal domain is required for cell surface localisation of VapA, a member of the Vap family of Rhodococcus equi virulence proteins. [PDF]
Rhodococcus equi pneumonia is an important cause of mortality in foals worldwide. Virulent equine isolates harbour an 80-85kb virulence plasmid encoding six virulence-associated proteins (Vaps).

VapC-1 of Nontypeable Haemophilus influenzae Is a Ribonuclease [PDF]
ABSTRACT Nontypeable Haemophilus influenzae (NTHi) organisms are obligate parasites of the human upper respiratory tract that can exist as commensals or pathogens. Toxin-antitoxin (TA) loci are highly conserved gene pairs that encode both a toxin and antitoxin moiety.

VapCs of Mycobacterium tuberculosis cleave RNAs essential for translation [PDF]
The major human pathogen Mycobacterium tuberculosis can survive in the host organism for decades without causing symptoms. A large cohort of Toxin-Antitoxin (TA) modules contribute to this persistence. Of these, 48 TA modules belong to the vapBC (virulence associated protein) gene family. VapC toxins are PIN domain endonucleases that, in enterobacteria,

Analysis of non-typeable Haemophilous influenzae VapC1 mutations reveals structural features required for toxicity and flexibility in the active site. [PDF]
Bacteria have evolved mechanisms that allow them to survive in the face of a variety of stresses including nutrient deprivation, antibiotic challenge and engulfment by predator cells.
