FliH and FliI help FlhA bring strict order to flagellar protein export in Salmonella

This study identifies the role of FlhA's GYXLI motif and the flagellar ATPase complex in regulating substrate specificity switching of the fT3SS during flagellar assembly in Salmonella.

Conserved GYXLI motif of FlhA is involved in dynamic domain motions of FlhA required for flagellar protein export

This study identifies the conserved GYXLI motif in FlhA as critical for dynamic domain motions in FlhAC, enabling efficient flagellar protein export via the fT3SS.

Native structure of flagellar MS ring is formed by 34 subunits with 23-fold and 11-fold subsymmetries

The paper determines the native structure of the bacterial flagellar MS ring, revealing it is 34-fold symmetric with 23-fold and 11-fold subsymmetries in its inner and middle regions.

The FlhA linker mediates flagellar protein export switching during flagellar assembly

The paper identifies FlhA's linker as a switch that regulates flagellar protein export specificity during assembly by interacting with FlhAC to control chaperone binding.

Membrane voltage-dependent activation of the flagellar protein export engine

The paper investigates how membrane voltage influences flagellar protein export by showing that a voltage increase recovers export in the absence of ion gradients.

The FlgN chaperone activates the Na+-driven engine of the flagellar protein export apparatus

The paper identifies FlgN as a chaperone that activates the Na+-driven export mechanism in the absence of the ATPase complex in bacterial flagellar protein export.

Stator remodeling mechanism of Bacillus subtilis flagellar motor during biofilm development

This study shows that the MotPS stator complex in Bacillus subtilis is essential for efficient biofilm maturation, despite not affecting swimming motility.
