[https://www.uniprot.org/uniprot/SCTC1_SALTY SCTC1_SALTY] Component of the type III secretion system (T3SS), also called injectisome, which is used to inject bacterial effector proteins into eukaryotic host cells (PubMed:9786184, PubMed:27974800, PubMed:30242280). Forms a ring-shaped multimeric structure with an apparent central pore in the outer membrane (PubMed:9786184, PubMed:21385715, PubMed:27974800, PubMed:30242280).<ref>PMID:21385715</ref> <ref>PMID:27974800</ref> <ref>PMID:30242280</ref> <ref>PMID:9786184</ref>

The T3SS injectisome is a syringe-shaped macromolecular assembly found in pathogenic Gram-negative bacteria that allows for the direct delivery of virulence effectors into host cells. It is composed of a "basal body", a lock-nut structure spanning both bacterial membranes, and a "needle" that protrudes away from the bacterial surface. A hollow channel spans throughout the apparatus, permitting the translocation of effector proteins from the bacterial cytosol to the host plasma membrane. The basal body is composed largely of three membrane-embedded proteins that form oligomerized concentric rings. Here, we report the crystal structures of three domains of the prototypical Salmonella SPI-1 basal body, and use a new approach incorporating symmetric flexible backbone docking and EM data to produce a model for their oligomeric assembly. The obtained models, validated by biochemical and in vivo assays, reveal the molecular details of the interactions driving basal body assembly, and notably demonstrate a conserved oligomerization mechanism.
