A ParDE-family toxin antitoxin system in major resistance plasmids of Enterobacteriaceae confers antibiotic and heat tolerance

Scientific Reports, 2019
Toxin-antitoxin (TA) systems were initially discovered as plasmid addiction systems on low-copy-number plasmids. Thousands of TA loci have since been identified on chromosomes, plasmids and mobile elements in bacteria and archaea with diverse roles in ...

Integrative Modeling in the Age of Machine Learning: A Summary of HADDOCK Strategies in CAPRI Rounds 47–55

Proteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT The HADDOCK team participated in CAPRI rounds 47–55 as server, manual predictor, and scorers. Throughout these CAPRI rounds, we used a plethora of computational strategies to predict the structure of protein complexes. Of the 10 targets comprising 24 interfaces, we achieved acceptable or better models for 3 targets in the human category and 1 ...

The VapBC-4 Characterization Indicates It Is a Bona Fide Toxin-Antitoxin Module of Leptospira interrogans: Initial Evidence for a Role in Bacterial Adaptation

Microorganisms
Toxin-antitoxin (TA) systems are one of the bacterial adaptation mechanisms to adverse conditions. Leptospira interrogans serovar Copenhageni contains nine putative TA systems.

Biomolecular Interaction Prediction in the Pre‐ and Post‐AlphaFold Era: The 8th CAPRI Evaluation

Proteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT We report on the 8th CAPRI Evaluation period, capturing the assessment of CAPRI Rounds 47 to 55 (excluding the CASP and COVID‐related Rounds), which have witnessed the transition to AI‐driven prediction tools such as AlphaFold and related alternatives. The prediction Rounds in this evaluation are characterized by a high level of difficulty due

Excitable dynamics through toxin-induced mRNA cleavage in bacteria.

PLoS ONE, 2019
Toxin-antitoxin (TA) systems in bacteria and archaea are small genetic elements consisting of the genes coding for an intracellular toxin and an antitoxin that can neutralize this toxin. In various cases, the toxins cleave the mRNA.

Novel polyadenylylation-dependent neutralization mechanism of the HEPN/MNT toxin/antitoxin system

Nucleic Acids Research, 2020
The two-gene module HEPN/MNT is predicted to be the most abundant toxin/antitoxin (TA) system in prokaryotes. However, its physiological function and neutralization mechanism remains obscure.

Oral Phageome as Potential Modulators of Periodontal Dysbiosis. A Systematic Review

Oral Diseases, EarlyView.
ABSTRACT Introduction The oral phageome, comprising bacteriophages inhabiting the oral cavity, has been proposed as a potential modulator of periodontal health and disease. This systematic review synthesizes current evidence on interactions between bacteriophages, key periodontal bacteria, and the host in periodontitis.

The MazEF Toxin-Antitoxin System Alters the β-Lactam Susceptibility of Staphylococcus aureus. [PDF]

PLoS ONE, 2015
Toxin-antitoxin (TA) systems are genetic elements of prokaryotes which encode a stable toxin and an unstable antitoxin that can counteract toxicity. TA systems residing on plasmids are often involved in episomal maintenance whereas those on chromosomes ...

From mouth to brain: Linking periodontal and peri‐implant dysbiosis to systemic inflammation and neuropathology

Periodontology 2000, EarlyView.
Abstract Background/Aim Growing evidence suggests that imbalances occurring within the human microbiota and deregulation of the host immune response may play a significant role in the development of neurodegenerative diseases. Materials and Methods A comprehensive narrative review of the latest experimental, clinical, and epidemiological insights was ...
