Type IV Secretion Systems

Multiprotein complexes that transport single proteins, multiprotein complexes, and nucleoprotein complexes from the CYTOPLASM into the EXTRACELLULAR SPACE or into recipient cells. T4SSs are found in GRAM-NEGATIVE BACTERIA, while homologous components to T4SSs are found in GRAM-POSTIVE BACTERIA.
