Exoenzyme S (ExoS) is a toxin directly translocated into eukaryotic cells by the type III secretory process of Pseudomonas aeruginosa. It is a bi-functional toxin and contain an N-terminal Rho GAP domain that disrupts the actin cytoskeleton and interference of phagocytosis. The C-terminal of ExoS contains an ADP-ribosyltransferase domain, which elicits a cytotoxic phenotype in cultured cells.

amino acids 366 to 453 ofPA3841 of ADP-rbosylating enzyme - Exoenzyme S overexpressed in a GST fusion. Afterwards cleaved with a help of trombin and separated on a polyacrylamide gel. Gel piece has been used for immunizations.

store at 4°C; make aliquots to avoid working with a stock. Please, remember to spin tubes briefly prior to opening them to avoid any losses that might occur from liquid material adhering to the cap or sides of the tubes.
