Membranes and organelles Editorial overview
Peter Rehling is professor and chair of biochemistry at the Faculty of Medicine at the University of Göttingen and the director of the Department for Biochemistry II. His laboratory studies the biogenesis of mitochondria, in particular the molecular mechanism by which proteins are translocated across the mitochondrial membranes and how they assemble into membrane protein complexes. In all cellu...
متن کاملMechanisms shaping the membranes of cellular organelles.
Cellular organelles have characteristic morphologies that arise as a result of different local membrane curvatures. A striking example is the endoplasmic reticulum (ER), which consists of ER tubules with high curvature in cross-section, peripheral ER sheets with little curvature except at their edges and the nuclear envelope with low curvature except where the nuclear pores are inserted. The ER...
متن کاملMechanisms for the incorporation of proteins in membranes and organelles
Because of the high degree of organizational complexity of eucaryotic cells, it is clear that the implementation of their genetic programs must, in many cases, involve a complex sequence of cotranslational and posttranslational events that are necessary to transfer polypeptides from their sites of synthesis to their sites of function. It is difficult to envisage the existence of a single genera...
متن کاملRibosomes, membranes and organelles during meiosis in angiosperms
Evidence is presented from both observational and analytical techniques indicating profound changes to take place in the ribosome population during male and female meiosis in some flowering plants. During microsporogenesis these appear to involve the elimination of the major part of the ribosome complement early in the meiotic prophase, and its subsequent restoration by the disintegration in th...
