Chains	Enzyme Name	Description	Catalytic Residues
A	mono-ADP-ribosyltransferase C3 M-CSA #824	Clostridium boltulinum C3 exoenzyme catalyses the transfer of the ADP-ribose moiety of NAD onto asparagine 41 of the small GTP-binding protein Rho. This ADP-ribosylation inactivates Rho, blocking Rho activity in regulating the cytoskeleton and leading to cytoskeleton depolymerisation. The protein synthesis inhibitors (inactivate the eukaryotic elongation factor 2 eEF2) diptheria toxin from Corynebacterium diphtheriae and exotoxin A (ETA) from Pseudomonas aeruginosa are also ADP-ribosyltransferases, contain a conserved Glu and thought to proceed through the same catalytic mechanism.
