Anti-ExoS | Exoenzyme S

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 of PA3841 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.
