abstract = {Bacterial type III protein secretion systems inject
effector proteins into eukaryotic host cells in order to
promote survival and colonization of Gram-negative pathogens
and symbionts. Secretion across the bacterial cell envelope
and injection into host cells is facilitated by a so-called
injectisome. Its small hydrophobic export apparatus
components SpaP and SpaR were shown to nucleate assembly of
the needle complex and to form the central “cup”
substructure of a Salmonella Typhimurium secretion system.
However, the in vivo placement of these components in the
needle complex and their function during the secretion
process remained poorly defined. Here we present evidence
that a SpaP pentamer forms a 15 Å wide pore and provide a
detailed map of SpaP interactions with the export apparatus
components SpaQ, SpaR, and SpaS. We further refine the
current view of export apparatus assembly, consolidate
transmembrane topology models for SpaP and SpaR, and present
intimate interactions of the periplasmic domains of SpaP and
SpaR with the inner rod protein PrgJ, indicating how export
apparatus and needle filament are connected to create a
continuous conduit for substrate translocation.},
