FIGURE 1.

Schematic representation of the P. aeruginosa FoxR protein. The P. aeruginosa FoxR protein has been drawn to scale, and the cytosolic, transmembrane, and periplasmic (FoxRperi) regions of the protein are detailed. The site where the self-cleavage of FoxR occurs (between Gly-191 and Thr-192; GT) and surrounding residues have been indicated. The numbers indicate amino acid positions in the FoxR protein. The N- and C-domains resulting from self-cleavage are illustrated. The exact cleavage sites of the Prc and RseP proteases are unknown.
