Description
Type III secretion systems (T3SS) are bacterial molecular assemblies employed to inject effector proteins in host cells. We present the structure of a T3S export gate with a substrate:chaperone complex. Following a divide-and-conquer strategy, we first determined the structure of the previously uncharacterized substrate:chaperone complex at higher resolution. Our ternary complex marks the first instance where the substrate directly binds to the export gate instead of mediation by the chaperone.
