The structural and functional illustrative model of T3SS nanomachine in Salmonella spp. SPI-1. In Salmonella SPI-1 T3SS, the needle complex, basal body, export apparatus, and sorting complex, are shown on the left side. The cross sections of the inner structure of these components are shown on the right side. On the right side, electron microscopy-mediated solved protein structures are compiled to display basic nanomachine orientations. SctC and SctD proteins transfer to the inner rod in the inner membrane and pass to the translocon or needle complex (SctF). Accession numbers from the Protein Data Bank (PDB) were used to search, and carton displays were created in Biorender. The proteins, accession IDs, and their names are listed as Needle complex. SctE (AopB-3WXX; and SipB-3TUL), SctA (SipD; PDB-3NZZ), SctF (PDB-3J0R), SctC; (PDB-5TCQ & 5TCR) (InvG); SctDN (PDB-3J1W) (InvG), SctDC; (PDB-5TCP), SctJ (PrgH-PrgK::PrgK; PDB-3J6D, − 5TCP; − 5TCR), SctU (SpaS; PDB-3C01, SpaSC), SctV (PDB-4A5P), SctO (PDB-3K29), SctN (PDB-2OBM) (Abrusci et al. 2013; Bergeron et al. 2013; 2015; Chatterjee et al. 2011; Fujii et al. 2012; Lorenzini et al. 2010; Worrall et al. 2008, 2016; Zarivach et al. 2007, 2008; Deng et al. 2017)
