FIGURE 9.

Comparison of the ExoU_{P. flu} and ExoU_{P. aer} structures. A, linear depiction of ExoU_{P. flu} and ExoU_{P. aer} domains. The putative chaperone binding domain (domain 1) is shown in green, the patatin PLA₂ domain (domain 2) in red, and the MLD in blue. The MLD is composed of domain 3 (light blue) and domain 4 (dark blue). Disordered regions in both structures are shown in white. B, domain-to-domain comparisons of the least squares superimposed ExoU_{P. flu} (colored as in A) and ExoU_{P. aer} (gray) structures.
