Genetic organizations of T6SS in Serratia and other bacteria.

, 2015
(A), (B), (C) and (D) show the genetic organizations of the 11 T6SS clusters found in Serratia, which have different organizations and separate into four families (T6SS-a, T6SS-b, T6SS-c and T6SS-d). T6SS-a was aligned across S.

Role of Klebsiella pneumoniae Type VI secretion system (T6SS) in long-term gastrointestinal colonization

, 2022
International audienceAbstract Type VI secretion systems (T6SS), recently described in hypervirulent K. pneumoniae (hvKp) strains , are involved in bacterial warfare but their role in classical clinical strains (cKp) has been little investigated .

Structure‐Based Annotation by AlphaFold3 Predictions of the Francisella halioticida T6SS Encoded in the Francisella Pathogenicity Island

Journal of Fish Diseases, EarlyView.
ABSTRACT Francisella halioticida has emerged as a significant pathogen of cultured molluscs, causing substantial economic losses due to mass mortalities. The Francisella Pathogenicity Island encodes a Type VI secretion system essential for virulence and intracellular persistence. However, the F.

Solving the puzzle: connecting a heterologous Agrobacterium tumefaciens T6SS effector to a Pseudomonas aeruginosa spike complex [PDF]

, 2020
The type VI secretion system (T6SS) is a contractile injection apparatus that translocates a spike loaded with various effectors directly into eukaryotic and prokaryotic target cells.

Type VI secretion system (T6SS) in Klebsiella pneumoniae, relation to antibiotic resistance and biofilm formation

Iranian Journal of Microbiology, 2023
Background and Objectives: The type VI secretion system (T6SS) was identified as a novel virulence factor in many Gram-negative bacteria. This study aimed to investigate the frequency of the T6SS genes in Klebsiella pneumoniae-causing different ...

Structure of the T6SS lipoprotein TssJ1 fromPseudomonas aeruginosa [PDF]

Acta Crystallographica Section F Structural Biology and Crystallization Communications, 2013
The type VI secretion system of Pseudomonas aeruginosa has been shown to be responsible for the translocation of bacteriolytic effectors into competing bacteria. A mechanistic understanding of this widely distributed secretion system is developing and structural studies of its components are ongoing.

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

Relay Architectures and Ecological Strategies of Quorum Sensing Effects on Microbial Interactions

Environmental Microbiology, Volume 28, Issue 10, October 2026.
Quorum‐sensing activity in one population affects neighbouring populations through direct signal perception, QS‐regulated chemical effectors, or host‐ or environment‐mediated relays. Across distinct habitats, these relay architectures are associated with ecological strategies ranging from shared signal accessibility and reciprocal responsiveness to ...
