  1. 1. Biogenesis and assembly of the mammalian mitochondrial inner membrane

    Författare :Antek Wielburski; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The aims of this investigation were to study the synthesis and assembly of mammalian mitochondrial inner membrane with emphasis on cytochrome c oxidase. Model systems utilizing rat hepatocytes and digitonin-treated hepatocytes were established for use in the investigation of mitochondrial protein synthesis in mammalian cells. LÄS MER

  3. 2. Mitochondrial Energy Metabolism : Kgd4 is a novel subunit of the α-ketoglutarate dehydrogenase complex

    Författare :Manfred Heublein; Martin Ott; Flavia Fontanesi; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mitochondria; α-ketoglutarate dehydrogenase; Kgd4; Krebs cycle; Biochemistry; biokemi;

    Sammanfattning : 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. LÄS MER

  4. 3. Membrane effects on proton transfer in cytochrome c oxidase

    Författare :Linda Näsvik Öjemyr; Peter Brzezinski; Anthony G. Lee; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cytochrom c oxidase; lipids; membrane; proton transfer; Biochemistry; biokemi;

    Sammanfattning : The biological membrane is composed of lipids and proteins that make up dynamic barriers around cells and organelles. Membrane-spanning proteins are involved in many key processes in the cell such as energy conversion, nerve conduction and signal transduction. LÄS MER

  5. 4. Characterization of mitochondrial membrane proteins as novel components in mitochondrial dynamics

    Författare :Tong Liu; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Mitochondria are dynamic organelles that frequently change their shape by shifting the balance of fusion and fission in response to cellular metabolic needs. This process is termed mitochondrial dynamics. Dysregulation of mitochondrial dynamics has been described in many human diseases. LÄS MER

  7. 5. Significance of mitochondrial ultrastructure for bioenergetics

    Författare :Alexandra Toth; Martin Ott; Vladimir Gogvadze; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; bioenergetics; mitochondrial ultrastructure; respiratory chain; Saccharomyces cereviciae; ATP synthase; apoptosis; cytochrome c; supercomplexes; Biochemistry; biokemi;

    Sammanfattning : Mitochondria are the site where most of the energy from food is converted into adenosine triphosphate (ATP). This process is taking place at the inner membrane (IM) of mitochondria, and is called oxidative phosphorylation, and results in the establishment of a proton motive force (pmf). LÄS MER
