== Publication Abstract from PubMed ==
 +
The mono-ADP-ribosyltransferase toxins are bacterial virulence factors that contribute to many disease states in plants, animals and humans. These toxins function as enzymes that target various host proteins and covalently attach an ADP-ribose moiety that alters target protein function. We tested compounds from a virtual screen of commercially available compounds combined with a directed PARP inhibitor library and found several compounds that bind tightly and inhibit toxins from Pseudomonas aeruginosa and Vibrio cholerae. The most efficacious compounds completely protected human lung epithelial cells against the cytotoxicity of these bacterial virulence factors. Moreover, we determined high-resolution crystal structures of the best inhibitors in complex with cholix toxin to reveal important criteria for inhibitor binding and mechanism of action. These results provide new insight in antivirulence compound development for treating many bacterial diseases.

[[http://www.uniprot.org/uniprot/Q5EK40_VIBCH Q5EK40_VIBCH]] An NAD-dependent ADP-ribosyltransferase (ADPRT), it catalyzes the transfer of the ADP-ribosyl moiety of oxidized NAD onto eukaryotic elongation factor 2 (eEF-2) thus arresting protein synthesis. It probably uses the eukaryotic prolow-density lipoprotein receptor-related protein 1 (LRP1) to enter mouse cells, although there seems to be at least one other receptor as well. Is active against mouse fibroblasts, Chinese hamster ovary eEF-2, brine shrimp (Artemia spp. nauplii) and upon expression in S.cerevisiae.<ref>PMID:18276581</ref> <ref>PMID:19793133</ref>
