Type IV secretion system: Overview, Function & Structure

The bacterial type IV secretion system, also known as the type IV secretion system or the T4SS, is a secretion protein complex found in gram negative bacteria, gram positive bacteria, and archaea. It is able to transport proteins and DNA across the cell membrane. The type IV secretion system is just one of many bacterial secretion systems. Type IV…
