Structures of P. aeruginosa ExoU and its chaperone, SpcU (PDB ID 3TU3), shown as a cartoon. SpcU is shown in white, the ExoU chaperone binding domain is in gold, the PLA2 domain is green, and the membrane localization domain is shown in pink and purple. Catalytically important residues are shown as yellow sticks, and the ubiquitylable Lys178 is shown as a space-filling representation.
