Part:BBa_K3788011

BBa_K3788011 is coding for pelB, sfGFP and AidaA-I (D>N). 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, the mutation of the 846 – 847 amino acid permit to no have protein cleavage, and attach this one to the extracellular membrane. 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 address to the preriplasm thanks to pelB leader and the T5SS system will address sfGFP to the extracellular membrane without cleavage. Sequence was optimised for E. coli K12.
