Introduction
Several bacteria, including E. coli, have been shown to produce vesicles for various reasons (METTRE UNE REF ET CITER QUELQUES RAISONS). In our project, we want to optimize vesicle production to develop a long distance communication system between gram-negative bacteria. Outer membrane vesicles (OMVs) production can be enhanced through the destabilization of the outer membrane. We found in the literature that the Tol/Pal system could be a good target for this purpose[1]. The Tol/Pal system of Escherichia Coli is required to maintain the outer membrane integrity. It is composed of five cell membrane proteins, TolA, TolB, TolQ, TolR and Pal, included in two complexes..[2][3]
See Tol/Pal part for more information and why we choose this system. Strategy and Construction part explains our aim in this OMV production system.
