A widespread family of chaperones functions to stabilize membrane protein effectors by mimicking transmembrane helical environments and promotes effector export by the bacterial type VI secretion system.

The death of bacterial kin cells releases a danger signal that activates a posttranscriptional response in surviving cells, resulting in the rapid elaboration of interbacterial competition factors.

A canonical class III adenylate cyclase with a membrane anchor of six transmembrane spans is regulated by a receptor of similar design, the quorum-sensing receptor from Vibrio harveyi.

Legionella pneumophila can be inhibited by its own antimicrobial, HGA (homogentisic acid), but its density-dependent resistance to HGA restricts the potential for self-harm.

A single mutation in Escherichia coli connects two essential cell envelope assembly pathways and confers vancomycin resistance by displaying molecular decoys at the cell surface.

The NAIP-NLRC4 inflammasome in intestinal epithelial cells protects mice from oral route Shigella infection.

Diverse LXG toxins delivered by the Esx pathway function as mediators of contact-dependent interbacterial antagonism within and between Gram-positive bacterial species.

Serial cell-to-cell transfer of lipoprotein toxins by outer membrane exchange provides a potent platform for kin discrimination in Myxococcus xanthus.

The bacterium Chlamydia trachomatis, a human pathogen, hijacks its host’s energy supplies by using the parasitophorous vacuole as a glycogen synthesis and storage compartment.
