Mechanism of translation inhibition by type II GNAT toxins: AtaT, TacT, and ItaT

ABSTRACT: Type II toxin-antitoxin (TA) systems are two-gene modules widely distributed among prokaryotes. GNAT toxins associated with the DUF1778 antitoxins represent a large family of type II TAs. GNAT toxins inhibit cell growth by disrupting translation via acetylation of aminoacyl-tRNAs. Using ribosome profiling, we investigated the in vivo substrate specificity of three GNAT toxins: AtaT2, TacT3, and ItaT.

The novel type II toxin-antitoxin PacTA modulates Pseudomonas aeruginosa iron homeostasis by obstructing the DNA-binding activity of Fur

Project description:Type II Toxin-antitoxin (TA) systems are widely distributed in bacterial and archaeal genomes with diverse critical cellular functions such as defense against phages, biofilm formation, persistence and virulence. GCN5-related N -acetyltransferase (GNAT) toxin, with an acetyltransferase activity-dependent mechanism of translation inhibition, represents a relatively new and expanding family of type II TA toxins. Here, we describe a group of GNAT-Xre TA modules that are widely distributed among Pseudomonas species and even certain Gram-positive bacteria. We investigate one of its members PacTA (encoded by PA3270/PA3269) from Pseudomonas aeruginosa, and demonstrate that the toxin PacT positively regulates the iron acquisition in P. aeruginosa. Notably, other than arresting translation via acetylating aminoacyl-tRNAs, PacT could directly bind to Fur, a key ferric uptake regulator, to attenuate its DNA-binding affinity and thus permit expression of downstream iron-acquisition-related genes. We further show that expression of the pacTA locus is up-regulated in response to iron starvation and the absence of PacT causes biofilm formation defect and attenuated pathogenesis. Overall, these findings reveal a novel regulation mechanism of GNAT toxin that controls genes involved in iron uptake process and contributes to the bacterial virulence.

Growth control switch by a DNA damage-inducible toxin-antitoxin system in Caulobacter

Project description:Bacterial toxin-antitoxin systems (TASs) are thought to respond to various stresses, often inducing growth-arrested (persistent) sub-populations of cells whose housekeeping functions are inhibited. However, it is not always clear whether specific targets of orthologous RNAse toxins are responsible for their phenotypic effect, which has made it difficult to accurately place the multitude of TASs within cellular and adaptive regulatory networks. Here we show that the TAS HigBA can promote and inhibit bacterial growth dependent on the dosage of HigB, a toxin regulated by the DNA damage (SOS) repressor LexA in addition to its antitoxin HigA, and the target selectivity of HigBâs mRNA cleavage activity. HigB reduced the expression of an efflux pump that is toxic to a polarity control mutant, cripples the growth of cells lacking LexA and targets the cell cycle circuitry. Thus, TASs can have outcome switching activity in bacterial adaptive (stress) and systemic (cell cycle) networks. DNA binding of the antitoxin HigA and the SOS regulator LexA was analysed by chromatin immunoprecipitation-deep sequencing, and found to overlap at only one locus, the HigBA TA system promoter

Transcription profiling of E. coli K-12 MG1655 and E. coli K-12 LVM100 delta 5 TA mutant effect on biofilm cell development

Project description:The role of six toxin-antitoxin (TA) systems on biofilm development was investigated (MazEF, RelBEF, ChpB, YefM-YoeB, DinJ-YafQ, and TomB-Hha). Although these TA systems were reported previously to not impact bacterial fitness, we found that biofilm formation is decreased by toxins and increased by anti-toxins, in part, through YjgK. Hence, one role of TA systems is to regulate biofilm formation. Experiment Overall Design: Strains: E. coli K-12 MG1655 and E. coli K-12 LVM100 delta 5 TA mutant Experiment Overall Design: Medium: LB Experiment Overall Design: Cells: biofilm cells on glass wool Experiment Overall Design: Time: 15 h Experiment Overall Design: Temperature: 37oC

VapCs of Mycobacterium tuberculosis Cleave RNAs Essential for Translation

Project description: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, inhibit translation by site-specific cleavage of initiator tRNA. In contrast, VapC20 of M. tuberculosis inhibits translation by site-specific cleavage of the universally conserved Sarcin-Ricin loop (SRL) in 23S rRNA. Here we identify cleavage targets for 12 VapCs from M. tuberculosis by applying UV-crosslinking and deep sequencing. Remarkably, these VapCs are all endoribo-nucleases that cleave RNA targets that are essential for decoding at the ribosomal A-site. Eleven VapCs cleave specific tRNAs while one exhibits SRL cleavage activity. These findings suggest that multiple vapBC modules contribute to the survival of M. tuberculosis in its human host by reducing the level of translation.

Staphylococcus aureus toxin-antitoxin system

Project description:Type I toxin-antitoxin (TA) systems are widespread genetic modules in bacterial genomes. They express toxic peptides whose overexpression leads to growth arrest or cell death, whereas antitoxins regulate the expression of toxins, acting as labile antisense RNAs. The Staphylococcus aureus (S. aureus) genome contains and expresses several functional type I TA systems, but their biological functions remain unclear. Here we addressed and challenged experimentally, by proteomics, if a type I TA system, the SprF1/SprG1 pair, influences the overall gene expression in S. aureus. Deleted and complemented S. aureus strains were analyzed for their proteomes, both intracellular and extracellular, during growth. Comparison of intracellular proteomes between the strains points on SprF1 antitoxin as an agent downregulating protein expression. In the strain naturally expressing the SprG1 toxin, cytoplasmic proteins are excreted into the medium, but this is not due to unspecific cell leakages. Such toxin-driven release of the cytoplasmic proteins may modulate the host inflammatory response that, in turn, may amplify the S. aureus infection spread.

Expression profile for overproduction of ArT

Project description:Toxin-antitoxin (TA) systems are ubiquitous throughout bacterial and archaeal genomes. TA systems consist of a stable toxin that inhibits growth and a labile antitoxin that prevents toxicity of the toxin. Here we made an artificial TA system (arT/arA) and performed a DNA microarray study for overproduction of the toxin.
