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.
