Their type III secretome and effector repertoire is crucial for our effort in elucidating the molecular pathogenesis mechanisms, as well as developing new therapeutics for these pathogens. In thisMolecular Cellular Proteomics 11.Type III Secretome of EPECFIG. 6. The LifA/Efa1/ToxB homologs are a new family of type III effectors in the A/E bacterial pathogens. The type III secretion assays and tr
