Exoenzymes (Exo) are secreted by cells and break large macromolecules outside the cells. The breakdown components can pass through the cell wall.
- Exo C3 is a Clostridium butulinum toxin which binds NAD, splits it into ADP-ribose and nicotinamide and transfers the ADP-ribose to a protein substrate.
- Exo S and Exo T are secreted by Pseudomonas aeruginosa and has GTPase-activating activity as well as ADP-ribosyltransferase activity[1] .
