Structural biology of type VI secretion systems. [PDF]
Philos Trans R Soc Lond B Biol Sci, 2012 Type VI secretion systems (T6SSs) are transenvelope complexes specialized in the transport of proteins or domains directly into target cells. These systems are versatile as they can target either eukaryotic host cells and therefore modulate the bacteria–host interaction and pathogenesis or bacterial cells and therefore facilitate access to a specific ...

Adaptor Proteins of Type VI Secretion System Effectors [PDF]
Trends in Microbiology, 2017 Bacteria use the type VI secretion system (T6SS) to kill neighboring cells. One key feature of the T6SS is the secretion of diverse effectors. Here, we discuss six publications that describe three superfamilies of T6SS proteins, each dedicated to mediate the secretion of cognate effectors.

Type VI Secretion System Helps Find a Niche [PDF]
Cell Host & Microbe, 2014 Type VI secretion systems (T6SSs) deliver toxins into target cells and thus play a role in bacterial warfare. In this issue of Cell Host & Microbe, Ma et al. (2014) demonstrate that T6SS-dependent attack during interbacterial competition in the host context enables niche colonization by Agrobacterium tumefaciens.

Bacterial type VI secretion system facilitates niche domination [PDF]
Proceedings of the National Academy of Sciences, 2018 Over the last few decades humanity has experienced a series of tremendous technological advances, especially in the realm of basic science. A plethora of new approaches has allowed us to appreciate life in previously unimaginable detail, prompting the realization that life in the microscopic world is not so different from what we can observe with our ...

Phage tail-like particles are versatile bacterial nanomachines – A mini-review
Journal of Advanced Research, 2019 Type VI secretion systems and tailocins, two bacterial phage tail-like particles, have been reported to foster interbacterial competition. Both nanostructures enable their producer to kill other bacteria competing for the same ecological niche ...

Structure of the Type VI Secretion System Contractile Sheath [PDF]
Cell, 2015 Bacteria use rapid contraction of a long sheath of the type VI secretion system (T6SS) to deliver effectors into a target cell. Here, we present an atomic-resolution structure of a native contracted Vibrio cholerae sheath determined by cryo-electron microscopy. The sheath subunits, composed of tightly interacting proteins VipA and VipB, assemble into a

Diversification of the Type VI Secretion System in Agrobacteria
mBio, 2021 The T6SS is used by several taxa of Gram-negative bacteria to secrete toxic effector proteins to attack others. Diversification of effector collections shapes bacterial interactions and impacts the health of hosts and ecosystems in which bacteria reside.

Analysis of the outer membrane proteome and secretome of Bacteroides fragilis reveals a multiplicity of secretion mechanisms. [PDF]
PLoS ONE, 2015 Bacteroides fragilis is a widely distributed member of the human gut microbiome and an opportunistic pathogen. Cell surface molecules produced by this organism likely play important roles in colonization, communication with other microbes, and ...
