RNA Regulated Toxin-Antitoxin Systems in Pathogenic Bacteria

Frontiers in Cellular and Infection Microbiology, 2021
The dynamic host environment presents a significant hurdle that pathogenic bacteria must overcome to survive and cause diseases. Consequently, these organisms have evolved molecular mechanisms to facilitate adaptation to environmental changes within the ...

Macromolecular High‐Affinity Binding Probed by Advanced Fluorescence Techniques

ChemBioChem, Accepted Article.
Due to the extreme sensitivity and the intrinsic selectivity of fluorescence techniques, high‐affinity binding can be measured even at extremely low molecule concentrations in the picomolar range. In particular, modern advanced techniques with fluorescence microscopes have provided considerable methodological advancements in recent years.

Hypothetical Functions of Toxin-Antitoxin Systems [PDF]

Journal of Bacteriology, 2007
Toxin-antitoxin systems are very commonly found both on large, low-copy plasmids, where they increase effective stability ([35][1]), and on bacterial chromosomes, where their function has been the subject of considerable speculation.

Regulation of toxin–antitoxin systems by proteolysis

Plasmid, 2013
Toxin-antitoxin systems are widely distributed among many bacterial species, including human pathogens. Typically, these systems consist of two genes in an operon which encodes a stable toxin disrupting essential cellular processes and a labile antitoxin preventing toxicity.

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 ...

Characterization of HicAB toxin-antitoxin module of Sinorhizobium meliloti

BMC Microbiology, 2019
Background Toxin-antitoxin (TA) systems are little genetic units generally composed of two genes encoding antitoxin and toxin. These systems are known to be involved in many functions that can lead to growth arrest and cell death.

Crystal Structure and Functional Characterization of YjgK From Salmonella Typhimurium

Proteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT The YhcH/YjgK/YiaL (DUF386) family, widely conserved across bacterial species, is involved in essential cellular processes yet remains poorly characterized. YjgK from Salmonella enterica serovar Typhimurium has drawn attention because of its potential role in biofilm formation associated with metal homeostasis, which may be critical for ...
