Show:Asymmetric Unit Biological Assembly Drag the structure with the mouse to rotate   Export Animated Image   Print3D 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 . NAD binding site.
