Mitochondria are endosymbiotic organelles essential for the oxidative energy metabolism of eukaryotic cells. Similar to Gram-negative bacteria, mitochondria contain an outer and an inner membrane and an own genome. However, only a handful of proteins are encoded in mitochondria. In addition, no membrane lipids are synthesized de novo within mitochondria. Therefore the vast majority of mitochondrial proteins and lipid precursors must be imported and we study the biogenesis of mitochondrial membranes.
