One of the current challenges in synthetic biology is the production of stable membrane mimetic systems and the insertion of components in these systems. Here, we employ fusion of oppositely charged liposomes to deliver separately reconstituted membrane proteins into a common lipid bilayer. After a systematic evaluation of different lipid compositions by lipid mixing and size distribution analysis, suitable conditions were further investigated for proteoliposome fusion. With this technique, we functionally coreconstituted bo3 oxidase and ATP synthase from Escherichia coli into unilamellar liposomes ranging from 100 nm to 50 μm in size. The presented method is a simple and versatile tool for oriented membrane protein reconstitution to produce biomimetic systems with increased complexity.
