Plants produce a high variety of secondary metabolites that are involved e.g. in plant-microbe interactions or are of pharmacological significance. However, the discovery, characterization and production of plant metabolites is often limited because these compounds usually accumulate at low amounts. Therefore, our focus here is to develop “synthetic microbes” for the production of such plant natural products. In this context the facultative photosynthetic bacterium Rhodobacter capsulatus will be established as an alternative expression host. During phototrophic growth, R. capsulatus forms a continuous system of intracytoplasmic membrane vesicles. This feature makes R. capsulatus a suitable platform host for the functional expression of plant-derived membrane bound enzymes and entire secondary metabolite pathways.
