Dynamic proton-dependent motors power Type IX secretion and gliding adhesin movement in Flavobacterium

A Tad-like apparatus is required for contact-dependent prey killing in predatory social bacteria

This study identifies a new type IV filament-like machinery, Kil, involved in contact-dependent prey killing by Myxococcus xanthus, showing its role in motility arrest and prey cell plasmolysis.

Central role and structure of the membrane pseudokinase YukC in the antibacterial Bacillus subtilis Type VIIb Secretion System.

This study investigates the Bacillus subtilis Type VIIb Secretion System (T7SSb), identifying YukC as a central pseudokinase subunit involved in secretion complex assembly and toxin recruitment.

A conserved motif of Porphyromonas Type IX secretion effectors C-terminal secretion signal specifies interactions with the PorKLMN core complex

The paper identifies a conserved C-terminal motif in Porphyromonas gingivalis T9SS effectors that mediates interaction with the PorKLMN core complex, revealing a conserved mechanism of substrate selection.

In situ and high-resolution Cryo-EM structure of the Type VI secretion membrane complex

The paper presents in situ cryo-EM structures of the T6SS membrane complex, revealing its 5-fold symmetry and new structural features.
