FOR 1805: Einfluss der Ribosomendynamik auf Regulation der Geschwindigkeit und Genauigkeit der Translation
Zusammenfassung der Projektergebnisse
Translation of the genetic information from a nucleotide sequence into a functional protein is a central biological process. The aim of this collaborative FOR1805 project was to uncover dynamic aspects of ribosome function in translation at different levels, from an atomic analysis to global-scale behavior. Using both prokaryotes and eukaryotes as model systems our results provide insights into common principles and divergent features in translation dynamics as well as regulation across the domains of life. We used a combination of interdisciplinary approaches, including high-resolution structural studies (single-particle/multi-particle cryo-EM), biophysical (rapid kinetics, molecular dynamics simulation, stochastic modeling), and biochemical (quantitative mass spectrometry, biochemical methods with singlemolecule and single-nucleotide resolution combined with the power of highly parallel deep sequencing) approaches. The team of scientists we have assembled consolidated the scientific expertise across Germany on ribosome function and protein translation. The individual projects used cutting-edge approaches and technologies, thus providing a multifaceted methodological spectrum to approach our complex scientific goal from multiple angles. Merging the research activities on translation across Germany and through this unique consolidated expertise collectively our results provided insights on (i) the role of various translation factors on the metastable energy landscape of the translating ribosome, (ii) the speed and accuracy in translation of single codon and whole open-reading frame, (iii) the impact of external factors (antibiotics, environmental stress) on translation fidelity and processivity, and (iv) the link between translation and protein folding, assembly and function. The strong collaborative nature of our research resulted in large number of publications. In total 70 original publications and 15 reviews were published from the individual projects with 15 original peerreviewed publications jointly co-authored by PIs from our Research Unit. Collectively, we generated unprecedented insights molecular aspects of the ribosome function and dynamics and advanced our understanding on how the ribosome, as a macromolecular machine, integrates different processes during translation and how how translation, as a crucial physiological process, controls cell vitality.
