Zusammenfassung der Projektergebnisse

Biological systems are constructed from elementary building blocks, and only their manifold and dynamic interplay provides the basis for life. To really understand this complexity, scientists need new approaches and tools. In this context, synthetic biology plays an important role because it focuses on the (re-)design of biological systems. This discipline is marked by highly creative approaches and requires a high degree of interdisciplinarity. The RTG2062 was built on internationally recognized working groups in biology, chemistry, and physics that were both experimentally and theoretically oriented and throve on interdisciplinary collaboration. This combination of factors allowed RTG2062 to offer a unique platform for emulating biological systems, creating functional synthetic modules, and training junior researchers in this new way of thinking and approaching research. RTG2062 research gained in visibility, as demonstrated by the successful International “Synthetic Biology” conference series “Synthetic Biology” (Synthetic Biology III in 2018), unique for the wide range of topics it covered. Still, RTG2062 was unable for covering all possible research areas in synthetic biology. Therefore, we decided to concentrate our activities in three research areas: generating synthetic cells and switches (area A), rationally designing and synthesizing molecular building blocks (area B), and reconstructing isolated biological parts and modules (area C). While at first glance these projects seem highly diverse, they all shared the same drive toward unravelling nature’s design principles for a deeper understanding of processes like photosynthesis, translational regulation, cell polarity and coat formation in prokaryotes. In addition, we were developing standardized biological parts, such as designer proteins and peptides, for potential application in medicine and biotechnology. Collaboration between disciplines allowed, for example, synthesis of nucleotides/genes, amino acids, and glyco-peptides by the chemistry groups. These compounds were required in projects addressing biological questions. Similarly, experts in gene expression worked together with plant scientists. It is this interdisciplinary work that has allowed us, on the one hand, to gain new insights into the design principles and mechanisms of nature and, on the other hand, to produce synthetic macromolecular units with new properties. Concurrently, RTG2062 offered junior researchers in the early stages of their careers vital methodological and conceptual training. The success of this unique setting resulted in the successful completion of 19 doctoral theses and 80 publications in high-impact journals. Particularly the numerous joint publications are an important indicator of how effective our bringing together groups from different disciplines has been in achieving synergistic progress in this new field of research.
