21. Organization of mitochondrial gene expression in yeast : Specific features of organellar protein synthesis
Abstract : Mitochondria contain their own genetic system, encoding key subunits of the oxidative phosphorylation system. These subunits are expressed by an organelle-specific gene expression machinery. READ MORE

22. Mitochondrial Energy Metabolism : Kgd4 is a novel subunit of the α-ketoglutarate dehydrogenase complex
Abstract : Mitochondria are essential organelles of eukaryotic cells and are responsible for their energy metabolism. The citric acid cycle, a chain of redox reactions in the mitochondrial matrix, is a central metabolic hub. READ MORE

23. Adaptive Evolution of the Bacterial Translation Machinery
Abstract : The process of protein synthesis via translation is of paramount importance for the existence of life on Earth. The bacterial translation machinery has embraced more than 3.5 billion years of molecular evolution to adapt and function efficiently under the provided physiological conditions. READ MORE

24. Dynamics of peptide chains during co-translational translocation, membrane integration & domain folding
Abstract : The biosynthesis of proteins occurs at the ribosomes, where amino acids are linked together into linear chains. Nascent protein chains may undergo several different processes during their synthesis. Some proteins begin to fold, while others interact with chaperones, targeting factors or processing enzymes.

25. Finding the unknowns in trans-translation
Abstract : Ribosomes stalled on problematic mRNAs can be rescued by a mechanism called trans-translation. This mechanism employs a dual transfer-messenger RNA molecule (tmRNA) together with a helper protein (SmpB). In this work we have used an in vitro translation system with pure components to further clarify the roles of tmRNA and SmpB in trans-translation. READ MORE
