Figure 1From: Type III secretion proteins PcrV and PcrG from Pseudomonas aeruginosa form a 1:1 complex through high affinity interactionsSequence alignment between PcrV ( P. aeruginosa ) and LcrV ( Y. pseudotuberculosis ), and PcrG and LcrG. Identical residues are highlighted, and the predicted coiled coil region in PcrV is identified with a green bar. The blue bar represents the major antigenic region of LcrV identified in active and passive immunization studies [12]. The arrow points to the end of the PcrG (1–74) construct.Back to article page
