AIDA-I autotransporter, linker + translocator domains
The cell envelope of gram-negative bacteria consists of two membranes, the cytoplasmic or inner membrane and the outer membrane. Transport of proteins across the inner membrane in most cases follows the general secretory pathway (GSP). Therefore, in gram-negative bacteria, proteins end up in the periplasm. To translocate proteins to the outer surface or into the supernatant, gram-negative bacteria have developed several distinct mechanisms. In contrast to the secretory systems that require a variety of specialized accessory proteins that, often in combination with the GSP, are responsible for the export of one or several passenger proteins into the supernatant, the autotransporter protein family members carry the export signal and machinery within a single polypeptide chain. The adhesin-involved-in-diffuse-adherence (AIDA) autotransporter has been identified as a virulence factor of the enteropathogenic Escherichia coli strain 2787 and predicted to be a member of the autotransporter protein family.
