This study reveals how core-sheath coupling in Leptospira flagella controls curvature and motility, showing its importance in viscous environments and infection.

The paper demonstrates that reprogramming phosphoryl flow directionality in bacterial phosphorelay systems can generate different dynamic responses, enabling programmable signaling dynamics.

This study shows that 5-aminolevulinic acid triggers shutdown of the HemKR signaling system in Leptospira by promoting HemK phosphatase activity, leading to gene expression changes and iron-deficit tolerance.
