Non-cognate immunity proteins provide broader defenses against interbacterial effectors in microbial communities

The paper demonstrates that immunity proteins can protect against non-cognate interbacterial effectors, challenging existing models of bacterial defense mechanisms.

The conserved serine transporter SdaC moonlights to enable self recognition

The paper identifies SdaC, a serine transporter, as a dual-function protein that enables self-recognition in Proteus mirabilis by coupling it with serine transport.

A family of contact-dependent nuclease effectors contain an exchangeable, species-identifying domain

The paper identifies a species-identifying domain in contact-dependent nuclease effectors and uses it to differentiate species in microbiomes.

Peer pressure from a Proteus mirabilis self-recognition system controls participation in cooperative swarm motility

The paper shows that Proteus mirabilis uses a non-lethal self-recognition system to exclude non-self cells from cooperative swarming by inducing a transient incompatible lifestyle.

Swarmer cell development of the bacterium Proteus mirabilis requires the conserved ECA biosynthesis gene, rffG

This study identifies rffG as essential for swarmer cell elongation and swarm motility in P. mirabilis, revealing its role in cell envelope integrity and RcsB-mediated stress response.

A proposed chaperone of the bacterial type VI secretion system functions to constrain a self-identity protein

The paper identifies IdsC as a chaperone that stabilizes IdsD clusters and facilitates its export via the T6S system in Proteus mirabilis.

A single point mutation in a TssB/VipA homolog disrupts sheath formation in the type VI secretion system of Proteus mirabilis

The paper identifies a single amino acid mutation in TssB that disrupts sheath formation in the T6S system of Proteus mirabilis, leading to impaired T6S activity.
