TssE

TssE is a protein component of the Type VI secretion system (TSS) found in various bacteria. The Type VI secretion system is a complex molecular machine that bacteria use to deliver effector proteins directly into target cells, which can include other bacteria or host cells. TssE plays a role in the assembly and function of this secretion system. It is often located within the baseplate of the TSS apparatus. This baseplate is a critical structure that anchors the system and is involved in the formation of the contractile sheath that drives effector protein delivery. Research has indicated that TssE interacts with other TSS components, such as TssK and TssL, to facilitate the proper assembly of the secretion machinery. The precise molecular mechanisms and interactions involving TssE are still areas of ongoing investigation, but its presence is considered essential for the functional integrity of the Type VI secretion system in many bacterial species. Understanding the role of TssE contributes to a broader comprehension of bacterial virulence mechanisms and inter-bacterial competition.
