Agrobacterium type IV secretion is a two-step process in which export substrates associate with the virulence protein VirJ in the periplasm.

Molecular microbiology - 1 Sept 2002

Pantoja Mario, Chen Lishan, Chen Yuching, Nester Eugene W

Abstract excerpt

Type IV secretion systems are virulence determinants in many bacteria and share extensive homology with many conjugal transfer systems. Although type IV systems and their homologues have been studied widely, the mechanism by which substrates are secreted remains unclear. In Agrobacterium, we show that type IV secretion substrates that lack signal peptides form a soluble complex in the periplasm with the virulence...
