A Quorum Sensing-Regulated Type VI Secretion System Containing Multiple Nonredundant VgrG Proteins Is Required for Interbacterial Competition in Chromobacterium violaceum

Microbiology Spectrum, 2022
The environmental pathogenic bacterium Chromobacterium violaceum kills Gram-positive bacteria by delivering violacein packed into outer membrane vesicles, but nothing is known about its contact-dependent competition mechanisms.

Characterization of multiple type-VI secretion system (T6SS) VgrG proteins in the pathogenicity and antibacterial activity of porcine extra-intestinal pathogenic Escherichia coli

Virulence, 2019
Porcine extra-intestinal pathogenic Escherichia coli (ExPEC) causes great economic losses to the pig industry and poses a serious threat to public health worldwide. Some secreted virulence factors have been reported to be involved in the pathogenicity of

Impact of hcp and vgrG on Acinetobacter baumannii biofilm formation during infection of human pulmonary alveolar epithelial cells [PDF]

Scientific Reports
The purpose of this research is to examine the impact of key type VI secretion system (T6SS) proteins hemolysin coregulated protein (Hcp) and valine-glycine repeat protein G (VgrG) on the metabolism of Acinetobacter baumannii (A. baumannii).

Pesticin-Like Effector VgrG3 cp Targeting Peptidoglycan Delivered by the Type VI Secretion System Contributes to Vibrio cholerae Interbacterial Competition

Microbiology Spectrum, 2023
Vibrio cholerae can utilize a type VI secretion system (T6SS) to increase its intra- and interspecies competition. However, much still remains to be understood about the underlying mechanism of this intraspecies competition. In this study, we isolated an
