iGEM > Paris > Vesicle production system > Overview
Introduction
Several gram-negative bacteria - including E. coli - have been shown to produce vesicles for various hypothetical reasons[1] (stress response, host-pathogen interaction...). 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[2]. The Tol/Pal system of Escherichia Coli is involved in anchoring the outer- to the inner-membrane and to the peptidoglycan layer. It is thus essential in maintaining membrane integrity. The system is composed of five membrane proteins (TolA, TolB, TolQ, TolR and Pal) associating in two complexes.[3][4]
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.
