Characterization of the ADP-ribosylation of actin by Clostridium botulinum C2 toxin and Clostridium perfringens iota toxin.
Clostridium botulinum C2 toxin and Clostridium perfringens iota toxin belong to a novel family of actin ADP-ribosylating toxins. ADP-ribosylation of actin inhibits actin polymerization and G-actin-associated ATPase activity. The ADP-form of actin is ADP-ribosylated at a higher rate than actin with bound ATP. ADP-ribosylation of actin is reversible, a reaction, which is accompanied by reconstitution of actin ATPase activity.
