pelB_sfGFP (without stop) _ aida-I

BBa_K3788026 is coding for pelB, sfGFP and AidaA. pelB is a leader sequence, it allows the protein to join the periplasm via the SEC system (unfolded proteins). Aida-I, on the other hand, is an autotransporter from the T5SS; it allow the addressing to the extracellular medium. In this contruction sfGFP permit to understand the mechanism, this protein can at the end be replaced by an other protein. sfGFP is supposed to be addressed to the preriplasm thanks to pelB leader sequence and the T5SS system will address sfGFP to the extracellular medium by making it go through a beta-barrel that lead it outside of the cell and then to cleave it. Sequence was optimised for E. coli K12.
