A DNase Type VI Secretion System Effector Requires Its MIX Domain for Secretion
Microbiology Spectrum, 2022 Gram-negative bacteria often employ the type VI secretion system (T6SS) to deliver diverse cocktails of antibacterial effectors into rival bacteria.

Microreview: type IV secretion systems: versatility and diversity in function [PDF]
, 2010 Type IV secretion systems (T4SSs) are large protein complexes which traverse the cell envelope of many bacteria. They contain a channel through which proteins or protein–DNA complexes can be translocated.

The rise of the Type VI secretion system [PDF]
F1000Prime Reports, 2013 Bacterial cells have developed multiple strategies to communicate with their surrounding environment. The intracellular compartment is separated from the milieu by a relatively impermeable cell envelope through which small molecules can passively diffuse, while larger macromolecules, such as proteins, can be actively transported.

Characterization of the SPI-1 and Rsp type three secretion systems in Pseudomonas fluorescens F113 [PDF]
, 2013 Pseudomonas fluorescens F113 is a plant growthpromoting rhizobacterium (PGPR) isolated from the sugar beet rhizosphere. The recent annotation of the F113 genome sequence has revealed that this strain encodes a wide array of secretion systems, including ...

Architecture and assembly of the Type VI secretion system
Biochimica et Biophysica Acta (BBA) - Molecular Cell Research, 2014 The Type VI secretion system (T6SS) delivers protein effectors to diverse cell types including prokaryotic and eukaryotic cells, therefore it participates in inter-bacterial competition and pathogenesis. The T6SS is constituted of an envelope-spanning complex anchoring a cytoplasmic tubular edifice.

A novel stabilization mechanism for the type VI secretion system sheath [PDF]
Proceedings of the National Academy of Sciences, 2021 Significance The T6SS is a microscopic harpoon that bacteria use to deliver toxins into neighboring cells. While its complex assembly process has been extensively studied, it remains unclear how the two forms (long and short) of the pivotal TssA protein affect T6SS function.

Type VI secretion system effectors: poisons with a purpose [PDF]
Nature Reviews Microbiology, 2014 The type VI secretion system (T6SS) mediates interactions between a broad range of Gram-negative bacterial species. Recent studies have led to a substantial increase in the number of characterized T6SS effector proteins and a more complete and nuanced view of the adaptive importance of the system.

PLoS Pathogens, 2014 The type VI secretion system (T6SS) is a widespread protein secretion system found in many Gram-negative bacteria. T6SSs are highly regulated by various regulatory systems at multiple levels, including post-translational regulation via threonine (Thr ...

Contact-independent killing mediated by a T6SS effector with intrinsic cell-entry properties
Nature Communications, 2021 Bacteria can use type VI secretion systems (T6SSs) to inject toxic effector proteins into adjacent cells, in a contact-dependent manner. Here, the authors provide evidence of contact-independent killing by a T6SS effector that is secreted into the ...
