Molecular Characterization of Protease Activity in Serratia sp. Strain SCBI and Its Importance in Cytotoxicity and Virulence [PDF]
A newly recognized Serratia species, termed South African Caenorhabditis briggsae isolate (SCBI), is both a mutualist of the nematode Caenorhabditis briggsae KT0001 and a pathogen of lepidopteran insects. Serratia sp.

sRNA Antitoxins: More than One Way to Repress a Toxin
Bacterial toxin-antitoxin loci consist of two genes: one encodes a potentially toxic protein, and the second, an antitoxin to repress its function or expression. The antitoxin can either be an RNA or a protein.

Shaping Pulses to Control Bistable Monotone Systems Using Koopman Operator [PDF]
In this paper, we further develop a recently proposed control method to switch a bistable system between its steady states using temporal pulses. The motivation for using pulses comes from biomedical and biological applications (e.g.

Toxin-antitoxin (TA) systems are small genetic elements composed of a toxin gene and its cognate antitoxin. The toxins of all known TA systems are proteins while the antitoxins are either proteins or non-coding RNAs. Based on the molecular nature of the antitoxin and its mode of interaction with the toxin the TA modules are currently grouped into five ...

Identification of a VapBC toxin–antitoxin system in a thermophilic bacterium Thermus thermophilus HB27 [PDF]
There are 12 putative toxin–antitoxin (TA) loci in the Thermus thermophilus HB27 genome, including four VapBC and three HicBA families. Expression of these seven putative toxin genes in Escherichia coli demonstrated that one putative VapC toxin TTC0125 ...

TOXIN-ANTITOXIN IMMUNIZATION AGAINST DIPHTHERIA [PDF]
The development of antitoxin in the bodies of animals injected with diphtheria toxin is one of the best established of facts. Since von Behring and Roux announced the results of their investigations, large numbers of horses have been injected with toxin and have developed abundant antitoxin.

Structural insights into chaperone addiction of toxin-antitoxin systems
SecB homologs can be associated with stress-responsive type II toxin–antitoxin (TA) systems and form tripartite toxin-antitoxin-chaperone systems (TAC).

Early childhood caries (ECC) involves cariogenic persisters that evade antimicrobial treatment. Persisters achieve this by downregulating heat shock proteins (HSPs) and formation of protein aggregates. Ti3C2 MXene‐based photothermal therapy (PTT) acts as a “nanothermal knife,” disrupting membranes, upregulating HSPs, inhibits aggregates, prevents ...

Toxin-Antitoxin Systems and Persistence
Toxin-antitoxin (TA) systems are small genetic modules comprising a stable toxic protein and an antitoxin preventing the toxin activity. In type II TA systems, antitoxins are unstable proteins that are degraded by host ATP-dependent proteases. In steady-state conditions, the antitoxin forms a complex with the toxin in which the toxic activity is ...
