== Publication Abstract from PubMed ==
 +
Salmonella spp. require the ADP-ribosyltransferase activity of the SpvB protein for intracellular growth and systemic virulence. SpvB covalently modifies actin, causing cytoskeletal disruption and apoptosis. We report here the crystal structure of the catalytic domain of SpvB, and we show by mass spectrometric analysis that SpvB modifies actin at Arg177, inhibiting its ATPase activity. We also describe two crystal structures of SpvB-modified, polymerization-deficient actin. These structures reveal that ADP-ribosylation does not lead to dramatic conformational changes in actin, suggesting a model in which this large family of toxins inhibits actin polymerization primarily through steric disruption of intrafilament contacts.

[[http://www.uniprot.org/uniprot/SPVB_SALCH SPVB_SALCH]] Mono-ADP-ribosylates eukaryotic muscle and non-muscle actin on 'Arg-177'. ADP-ribosylation prevents the polymerization of G-actin to F-actin, causing actin filament depolymerization, destruction of the cytoskeleton and cytotoxicity. Does not possess NAD(+)-glycohydrolase activity, unlike most mART enzymes (By similarity).
