Type III Secretion Systems

Multiprotein transmembrane complexes in GRAM-NEGATIVE BACTERIA involved in either the secretion of effector proteins from the bacterial cytoplasm into host cells, or the secretion and assembly of flagellar components. The major component of the T3SSs is called the injectosome or needle complex.
