Figure 1

Protein interaction network between type VI secretion subunits. The localization and topologies of the core components of the T6SS are represented. Arrows indicate interactions detected among the subunits by biochemical/structural (blue) or two-hybrid approaches (red). The letter accompanying the arrow denotes the system where the interaction was detected. The membrane-associated subassembly and the bacteriophage-like subassembly are outlined in green and pink, respectively. The question mark represents subunits for which the localization has not been investigated. Relevant studies are discussed in the text.
