Prediction of Toxin-Antitoxin system (TA system) as a Novel Potent Target in Salmonella typhi Using Bioinformatics Analysis
Background and Objective: Salmonella typhi is one of the major challenges for the human and animal health. Salmonella with high pathogenicity can be harmful factor for human health. The control of this pathogen is a big challenge as it can cause serious infectious diseases such as gastroenteritis, septicemia and typhoid fever. On the other side, there are many factors such as toxin-antitoxin (T...
متن کاملThe mazEF toxin-antitoxin system as a novel antibacterial target in Acinetobacter baumannii
Although analysis of toxin-antitoxin (TA) systems can be instructive, to date, there is no information on the prevalence and identity of TA systems based on a large panel of Acinetobacter baumannii clinical isolates. The aim of the current study was to screen for functional TA systems among clinical isolates of A. baumannii and to identify the systems' locations. For this purpose, we screened 8...
متن کاملEvolution of the SpoIISABC Toxin-Antitoxin-Antitoxin System in Bacilli
Programmed cell death in bacteria is generally associated with two-component toxin-antitoxin systems. The SpoIISABC system, originally identified in Bacillus subtilis, consists of three components: a SpoIISA toxin and the SpoIISB and SpoIISC antitoxins. SpoIISA is a membrane-bound protein, while SpoIISB and SpoIISC are small cytosolic antitoxins, which are able to bind SpoIISA and neutralize it...
متن کاملBacterial Toxin-antitoxin Systems Translation Inhibitors Everywhere the Toxin-antitoxin System Framework the Selfish Nature of Toxin-antitoxin Systems
*Correspondence to: Laurence Van Melderen; Email: [email protected] Toxin-antitoxin (TA) systems are composed of two elements: a toxic protein and an antitoxin which is either an RNA (type I and III) or a protein (type II). Type II systems are abundant in bacterial genomes in which theymove via horizontal gene transfer. They are generally composed of two genes organized in an operon, encoding ...
متن کاملThe phage abortive infection system, ToxIN, functions as a protein-RNA toxin-antitoxin pair.
Various mechanisms exist that enable bacteria to resist bacteriophage infection. Resistance strategies include the abortive infection (Abi) systems, which promote cell death and limit phage replication within a bacterial population. A highly effective 2-gene Abi system from the phytopathogen Erwinia carotovora subspecies atroseptica, designated ToxIN, is described. The ToxIN Abi system also fun...
