WebJun 14, 2024 · The T6SS is a molecular weapon broadly distributed among gram-negative bacteria that acts analogously to a speargun, delivering long pointed tubular structures into nearby neighboring host or bacterial cells ( 5, 6 ). WebDec 15, 2024 · Deletion of either rhs gene has little effect on T6SS-1 activity, but mutants lacking both rhsA and rhsB are defective for Hcp1 secretion and no longer inhibit target bacteria. Although ∆rhsA ∆rhsB mutants lose T6SS-1−mediated inhibition activity, they still assemble and fire contractile sheaths at a significantly reduced frequency. We ...
WebMar 11, 2024 · All these elements are packed into a T6SS sheath and are propelled out of the bacterial cell and into target cells. Vibrio cholerae VgrG-1 is the first identified T6SS effector, which is secreted by T6SS and displays a C-terminal actin cross-linking domain upon its translocation into phagocytic target cells (Pukatzki et al., 2007; Ma et al., 2009). WebDec 22, 2024 · Pseudomonas aeruginosa is an opportunistic pathogen with multiple strategies to interact with other microbes and host cells, gaining fitness in complicated infection sites. The contact-dependent type VI secretion system (T6SS) is one critical secretion apparatus involved in both interbacterial competition and pathogenesis.
WebMar 28, 2024 · This hyper-permeability phenotype is T6SS-dependent, indicating that the mutants are intoxicated by Tle delivered from neighboring sibling cells rather than by internally produced phospholipase. Unexpectedly, an in-frame deletion of tli does not induce hyper-permeability because Δ tli null mutants fail to deploy active Tle. WebDec 5, 2024 · The type VI secretion system (T6SS) is used by many bacteria to engage in social behavior and can affect the health of its host plant or animal. Because activities associated with T6SSs are often costly, T6SSs must be tightly regulated. However, our knowledge regarding how T6SS assembly and contraction are regulated remains limited.
