Structural insight into sodium ion pathway in the bacterial flagellar stator from marine Vibrio

The paper determines the structure of the Na+-driven stator PomAB from Vibrio using cryo-EM and reveals the sodium ion pathway, ion selectivity mechanism, and inhibition by phenamil.

Structural analysis of S-ring composed of FliFG fusion proteins in marine Vibrio polar flagellar motors

The paper reports the near-atomic structure of the S-ring from Vibrio alginolyticus flagellar motor using cryo-EM, revealing structural differences compared to Salmonella.

ATP dependent polymerization dynamics of bacterial actin proteins involved in Spiroplasma swimming

The paper investigates the structure, ATPase activity, and polymerization dynamics of two MreB homologs in Spiroplasma eriocheiris, finding differences in their polymerization behavior and ATP hydrolysis mechanisms.

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.

Thick perirenal fat predicts the growth pattern of renal cell carcinoma

This study finds that thick perirenal fat is associated with outward tumor protrusion in renal cell carcinoma.

Second harmonic generation polarization microscopy as a tool for protein structure analysis

This paper demonstrates the use of SHG polarization microscopy to detect protein conformational changes in macromolecular assemblies without labeling.
