Article Abstract:

Type III secretion systems or chaperones participate in the export of virulence proteins and flagellar components in Gram-negative bacteria. Data demonstrate that chaperones also mediate translation of the secreted proteins and together with chaperone FlgM, they exhibit both mRNA and amino acid secretion signals.
