'''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<ref>PMID:11114250</ref> .
