Molecular characterization and assembly of the needle complex of the Salmonella typhimurium type III protein secretion system. Kubori et al. (2000)

In this paper the authors isolate, purify and determine that PrgI is the main subunit of the T3SS

Fig.6 InvC showed significant similarity to proteins related to catalytic sub units of F0F1 ATPases and proteins required for export of flagellar proteins

"All strains were derived from the nonflagellated S. typhimurium strain SJW2941" InvG, PrgH, and PrgK Are Components of the Base Substructure of the Needle Complex. Fig 2

Figure 1 shows the difference between the wild type the mutated InvA protein which leads to a change in the needle complex formed by the type III secretion protein-export mechanism found in S. typhimurium.
