Protein binding between PcrG-PcrV and PcrH-PopB/PopD encoded by the pcrGVH-popBD operon of the Pseudomonas aeruginosa type III secretion system

Of the proteins encoded by the pcrGVH-popBD operon of the Pseudomonas aeruginosa type III secretion system, PcrG bound to PcrV and PcrH bound to PopB/PopD. In addition, Yersinia LcrG bound to PcrV, and Yersinia LcrH bound to PopD. The results imply a highly functional conservation of type III secretion between P. aeruginosa and Yersinia species.
