Background: VahC toxin from Aeromonas hydrophila inactivates actin by transferring ADP-ribose from NAD+. Results: The crystal structure of VahC reveals new insights into the interaction of the actin substrate with the actin-targeting toxins, and consequently, potent inhibitors have been developed. Conclusion: Broad spectrum inhibitors have been developed against actin-targeting toxins from the ADP-ribosyltransferase family. Significance: This new insight provides impetus for therapeutic development for treating bacterial diseases.
