Photosynthetic eukaryotes are among the most ancient and diverse organisms on the planet. They resulted from rounds of endosymbiotic events and have evolved to adapt to a wide range of environments. We focus on the detailed knowledge of the bionenergetic complexes structures from single components as well as their interaction into higher order associates, e.g. supercomplexes, to further understand the mechanisms behind the energetic metabolism. Our goal: The bioenergetics processes cannot be fully understood without a detailed knowledge of the structure and function of its single components as well as their interaction into higher order associates, like supercomplexes, where proper supramolecular organization is crucial to maintain high efficiency of the transfer processes. To further understand the mechanisms behind the energetic metabolism interactions in photosynthetic eukaryotes, a close characterization of the bionenergetic complexes is necessary. Our group is interested in the interconnection of Basic Science with Biomedicine and Biotechnology through several crossed-projects.
