Prevalence of Fst-like toxin–antitoxin systems [PDF]

open access: yesMicrobiology, 2010
Toxin–antitoxin (TA) systems are widespread in Gram-negative bacteria, and all systems identified to date encode a toxic protein and an unstable antitoxin, which may be in the form of either an antisense RNA (type I) or a second protein (type II). The enterococcal plasmid pAD1-encoded TA system (par), encoding the Fst toxin, was the first type I TA ...

Small Open Reading Frames, Non-Coding RNAs and Repetitive Elements in Bradyrhizobium japonicum USDA 110 [PDF]

open access: yes, 2016
Small open reading frames (sORFs) and genes for non-coding RNAs are poorly investigated components of most genomes. Our analysis of 1391 ORFs recently annotated in the soybean symbiont Bradyrhizobium japonicum USDA 110 revealed that 78% of them contain ...

Multiple Toxin-Antitoxin Systems in Mycobacterium tuberculosis [PDF]

open access: yesToxins, 2014
The hallmark of Mycobacterium tuberculosis is its ability to persist for a long-term in host granulomas, in a non-replicating and drug-tolerant state, and later awaken to cause disease. To date, the cellular factors and the molecular mechanisms that mediate entry into the persistence phase are poorly understood. Remarkably, M.

Reassessing the Role of the Type II MqsRA Toxin-Antitoxin System in Stress Response and Biofilm Formation: mqsA Is Transcriptionally Uncoupled from mqsR

open access: yesmBio, 2019
Toxin-antitoxin (TA) systems are broadly distributed modules whose biological roles remain mostly unknown. The mqsRA system is a noncanonical TA system in which the toxin and antitoxins genes are organized in operon but with the particularity that the ...

Complete Assembly of the Genome of an Acidovorax citrulli Strain Reveals a Naturally Occurring Plasmid in This Species [PDF]

open access: yes, 2019
Acidovorax citrulli is the causal agent of bacterial fruit blotch (BFB), a serious threat to cucurbit crop production worldwide. Based on genetic and phenotypic properties, A.

The Cysteine Protease MaOC1, a Prokaryotic Caspase Homolog, Cleaves the Antitoxin of a Type II Toxin-Antitoxin System

open access: yesFrontiers in Microbiology, 2021
The bloom-forming cyanobacterium Microcystis aeruginosa is known for its global distribution and for the production of toxic compounds. In the genome of M.

Induced ectopic expression of HigB toxin in Mycobacterium tuberculosis results in growth inhibition, reduced abundance of a subset of mRNAs and cleavage of tmRNA. [PDF]

open access: yes, 2013
In Mycobacterium tuberculosis, the genes Rv1954A-Rv1957 form an operon that includes Rv1955 and Rv1956 which encode the HigB toxin and the HigA antitoxin respectively.

Hypothetical Functions of Toxin-Antitoxin Systems [PDF]

open access: yesJournal 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.
