An expanded LPS translocon mediates surface lipoprotein export in the Bacteroidota

The paper identifies an expanded LPS translocon in Bacteroidota bacteria that mediates surface lipoprotein export, revealing structural and functional differences from the E. coli system.

Structure of the conjugation surface exclusion protein TraT

The paper reports the cryoEM structure of TraT, an outer membrane protein involved in plasmid exclusion, and suggests it functions by physical interference rather than specific protein interactions.

Structure and substrate recognition by the Twin-arginine translocation (Tat) pathway core complex

The paper presents structures of the Tat core complex in resting and substrate-bound states, revealing how substrate proteins interact with the complex through their signal peptides and proposing a model for early transport steps.

A novel shared mechanism for Bacteroidota protein transport and gliding motility

The paper identifies a shared mechanism between Bacteroidota gliding motility and T9SS protein transport involving disulfide-bonded outer membrane proteins.

A new structural paradigm for outer membrane protein biogenesis in the Bacteroidota

This study reports the cryoEM structure of a BAM complex from Flavobacterium johnsoniae, revealing a novel structural paradigm for outer membrane protein biogenesis in Bacteroidota.
