• Focuses on AIDA-I protein which is an an autotransporter naturally expressed in e coli
• Discusses applications using AIDA-1: expressing enzymes(whole cell biocatalysis), enzyme inhibitors(library screening), and epitotes(vaccine development)
• Interesting note: passenger proteins can dimerize on the cell surface

• Autotransporter = N-terminal signal peptide + passenger domain + translocator domain
• Study of autotransporters encourage because of their simplicity
• Possible issues with autotransporters
  • Passenger must be in "translocation-competent state" in periplasm
  • Need specific signal sequences
  • Host can introduce genetic background
• Other systems: Omp85, LamB, OmpA, PhoE, OmpC, TraT, FhuA, and intimin
• Autotransporters (AT) belong to type V secretion system, specifically the type Va branch
• Form beta-barrel to stabilize protein in the outer membrane
• Passenger can undergo some level of folding in the periplasm
• Most passenger domains are cleaved into media
• "System is not amenable to the display of eukaryotic cDNA libraries."
• 50,000 - 100,000 copies per cell

• "No energy coupling or accessory factors are known to be required for the translocation process"
• Some interesting autotransporters in e coli
