Prophage encoding toxin/antitoxin system PfiT/PfiA inhibits Pf4 production in Pseudomonas aeruginosa

Microbial Biotechnology, Volume 13, Issue 4, Page 1132-1144, July 2020., 2020
PfiT/PfiA in Pf4 prophage forms a type II toxin‐antitoxin system in Pseudomonas aeruginosa. PfiT inhibits production of Pf4 phage. Summary Pf prophages are ssDNA filamentous prophages that are prevalent among various Pseudomonas aeruginosa strains. The genomes of Pf prophages contain not only core genes encoding functions involved in phage replication,

Host‐specific competitiveness to form nodules in Rhizobium leguminosarum symbiovar viciae

New Phytologist, Volume 226, Issue 2, Page 555-568, April 2020., 2020
Summary Fabeae legumes such as pea and faba bean form symbiotic nodules with a large diversity of soil Rhizobium leguminosarum symbiovar viciae (Rlv) bacteria. However, bacteria competitive to form root nodules (CFN) are generally not the most efficient to fix dinitrogen, resulting in a decrease in legume crop yields.

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.

Protective immune response against Rhodococcus equi: An innate immunity‐focused review

Equine Veterinary Journal, Volume 57, Issue 3, Page 563-586, May 2025.
Abstract Rhodococcus equi causes pyogranulomatous pneumonia in foals and immunocompromised people. Despite decades of research efforts, no vaccine is available against this common cause of disease and death in foals. The purpose of this narrative review is to summarise the current understanding of interactions between R. equi and the host innate immune

Disorganized thalamic subregional functional connectivity in bipolar I disorder

MedComm, Volume 5, Issue 11, November 2024.
FIGURE 1 Flowchart of inclusion and exclusion criteria, and resting‐state functional connectivity (FC) analysis of subcortical regions and thalamic subregions. A total of 151 participants were enrolled. All participants were scanned with high‐resolution MRI. After data collection, preprocessing and seed‐based FC analysis were then performed.

Crystal structure of proteolyzed VapBC and DNA‐bound VapBC from Salmonella enterica Typhimurium LT2 and VapC as a putative Ca ²⁺ ‐dependent ribonuclease [PDF]

The FASEB Journal, 2019
Abstract Bacterial toxin‐antitoxin (TA) system has gained attention for its essential roles in cellular maintenance and survival under harsh environmental conditions such as nutrient deficiency and antibiotic treatment. There are at least 14 TA systems in Salmonella enterica

High‐quality genome of a novel Thermosynechococcaceae species from Namibia and characterization of its protein expression patterns at elevated temperatures

MicrobiologyOpen, Volume 13, Issue 5, October 2024.
In this study, the genome of a new thermophilic cyanobacterium, Thermosynechococcaceae cyanobacterium sp. Okahandja, isolated from a hot spring near Okahandja in Namibia, was sequenced. Additionally, cultivations were conducted at elevated temperatures of 40, 50, and 55°C, followed by analyses of the respective adapted proteomes based on the annotated ...

Automated discovery and phylogenetic analysis of new toxin-antitoxin systems

BMC Microbiology, 2008
Background Although often viewed as elements "at the service of" bacteria, plasmids exhibit replication and maintenance mechanisms that make them purely "selfish DNA" candidates.
