Campylobacter jejuni type VI secretion system: roles in adaptation to deoxycholic acid, host cell adherence, invasion, and in vivo colonization. [PDF]

PLoS ONE, 2012
The recently identified type VI secretion system (T6SS) of proteobacteria has been shown to promote pathogenicity, competitive advantage over competing microorganisms, and adaptation to environmental perturbation.

CueR regulates the expression of H2-T6SS directly and is required for H2-T6SS-mediated antibacterial activity.

, 2019
(A) Deletion of cueR increases the levels Hcp2 (upper) and TssA2 (down) relative to wild-type PAO1. Western blot analysis of Hcp2-Flag and TssA2-Flag in the cell-associated fractions from wild-type PAO1, ΔcueR, and the complemented strain (ΔcueR/p-cueR ...

In Planta Colonization and Role of T6SS in Two Rice Kosakonia Endophytes [PDF]

Molecular Plant-Microbe Interactions®, 2020
Endophytes live inside plants and are often beneficial. Kosakonia is a novel bacterial genus that includes many diazotrophic plant-associated isolates. Plant–bacteria studies on two rice endophytic Kosakonia beneficial strains were performed, including comparative genomics, secretome profiling, in planta tests, and a field release trial.

The Type VI Secretion Systems in Plant-Beneficial Bacteria Modulate Prokaryotic and Eukaryotic Interactions in the Rhizosphere

Frontiers in Microbiology, 2022
Rhizosphere colonizing plant growth promoting bacteria (PGPB) increase their competitiveness by producing diffusible toxic secondary metabolites, which inhibit competitors and deter predators.

Genetic Dissection of the Type VI Secretion System in Acinetobacter and Identification of a Novel Peptidoglycan Hydrolase, TagX, Required for Its Biogenesis

mBio, 2016
The type VI secretion system (T6SS) is a widespread secretory apparatus produced by Gram-negative bacteria that has emerged as a potent mediator of antibacterial activity during interbacterial interactions.

Beyond antimicrobials: Ecological nano‐strategies for rebalancing dysbiotic oral microbial homeostasis

BMEMat, EarlyView.
Oral microbial homeostasis, a dynamic host‐microbe balance, is vital in infectious diseases. Conventional antibiotics often disrupt this homeostasis, spurring interest in nanomaterials for oral microbial homeostasis rebalancing. This review outlines nanomaterial strategies across three ecological levels (population/community, ecosystem, and cross ...

The Campylobacter jejuni Type VI Secretion System Enhances the Oxidative Stress Response and Host Colonization

Frontiers in Microbiology, 2019
The role of the Type VI secretion system (T6SS) in Campylobacter jejuni is poorly understood despite an increasing prevalence of the T6SS in recent C. jejuni isolates in humans and chickens.

The Lord of the Rings: Cysteine bonds crosslink the tail of siphovirus

Protein Science, Volume 35, Issue 10, October 2026.
Abstract Long, non‐contractile tails composed of helical hexameric protein repeats that assemble into continuous tubular structures characterize siphoviruses. The siphovirus tail tube protein gp39 contains two cysteine residues per monomer. Cryo‐electron microscopy revealed that these cysteines are oriented toward the interface between the rings, which
