Covalently linked peptides and membrane potential enable CyaA segment translocation

Gaia Scilironi, Nicolas Carvalho, Jacinthe Frangieh…·Alexandre Chenal

This study investigates the translocation mechanisms of two CyaA-derived peptides, showing that P454 translocates independently of membrane potential while P233 requires a negative potential, and their covalent linkage enables translocation without potential.

Post-translational acylation drives folding and activity of the CyaA bacterial toxin.

Corentin C. Leger, Samuel Hoff, Gaia Scilironi…·Alexandre Chenal

This study shows that acylation stabilizes the native fold of CyaA and facilitates its membrane orientation, revealing how post-translational modification drives toxin activity.
