Rho proteins, which are involved in receptor-mediated regulation of the actin cytoskeleton, are substrates for ADP-ribosylation by Clostridium botulinum C3 toxins. Recently, it was shown that Rho and other members of the Rho subfamily of low-molecular-mass GTP-binding proteins are glucosylated by C. difficile toxins A and B. Glucosylation occurs at threonine-37, which is a crucial amino acid residue for the regulatory functions of the small GTP-binding proteins. These toxins should prove useful… CONTINUE READING
