WebFeb 12, 2014 · The type III secretion system (T3SS) is a protein delivery system which is involved in a wide spectrum of interactions, from mutualism to pathogenesis, between Gram negative bacteria and various eukaryotes, including plants, fungi, protozoa and mammals. Various phylogenetic families of the T3SS have been described, including the … WebSeveral bacterial pathogens make use of a specialized protein secretion system to inject effector proteins into host cells. This system, commonly referred to as type III secretion, is always associated with phenotypes related to intimate interactions between the pathogen and its respective host cells.
