Pseudomonas aeruginosa is an opportunistic bacterial pathogen of great medical relevance. One of its major toxins, exoenzyme S (ExoS), is a dual function protein with a C-terminal Ras-ADP-ribosylation domain and an N-terminal GTPase activating protein (GAP) domain specific for Rho-family proteins. We report here the three-dimensional structure of the N-terminal domain of ExoS determined by X-ray crystallography to 2.4 A resolution. Its fold is all helical with a four helix bundle core capped by additional irregular helices. Loops that are known to interact with Rho-family proteins show very large mobility. Considering the importance of ExoS in Pseudomonas pathogenicity, this structure could be of interest for drug targeting.
