Chaperone structure is not a sufficient determinant for the hierarchy of substrate secretion in bacterial type III secretion systems
Functional type III secretion in Gram negative bacteria relies on precise substrate targeting and a strict order of secretion with early, intermediate, and late substrates. Type III secretion chaperones facilitate these processes by maintaining substrates in a partially unfolded, secretion-competent state and serving as order-specific targeting factors. Early needle filament assembling substrates…
