  1. 1. Proton transfer across and along biological membranes

    Författare :Johan Berg; Peter Brzezinski; Artur Osyczka; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; biological membranes; cardiolipin; cytochrome bo3; cytochrome c oxidase; energy conversion; fluorescence correlation spectroscopy FCS ; localized coupling; mitochondria; proton transfer; Rcf1; respiration; single-enzyme measurement; Biochemistry; biokemi;

    Sammanfattning : Proton-transfer reactions belong to the most prevalent reactions in the biosphere and make life on Earth possible, as they are central to energy conversion. In most known organisms, protons are translocated from one side of a membrane to the other, which generates an electrochemical gradient that drives ATP synthesis. LÄS MER

  3. 2. Protein and lipid interactions within the respiratory chain : Studies using membrane-mimetic systems

    Författare :Tobias Nilsson; Peter Brzezinski; Petra Hellwig; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Cytochrome c oxidase; ATP synthase; Bioenergetics; membrane-mimetics; Rcf1; liposomes; oxidative phosphorylation; lipids; protein-protein interactions; Biochemistry; biokemi;

    Sammanfattning : Energy conversion from nutrients to ATP is a vital process in cells. The process, called oxidative phosphorylation (OXPHOS) is performed by a combination of membrane-bound proteins. These proteins have been studied in great detail in the past, however much is still unknown about how they interact with each other. LÄS MER

  4. 3. Structural studies on the integral membrane protein, ubiquinol oxidase from Escherichia coli

    Författare :Jeff Abramson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; crystal structure; ubiquinol oxidase; membrane protein; oxidases; Biokemi; Biochemistry; Biokemi; biokemi; Biochemistry;

    Sammanfattning : Heme-copper oxidases are redox-driven proton pumps that couple the reduction of molecular oxygen to water with the vectorial translocation of protons across the membrane. The proton gradient generated by heme-copper oxidases and the other members of the aerobic respiratory chain is ultimately used to drive the synthesis of ATP. LÄS MER

  5. 4. The social life of a membrane protein; It's complex

    Författare :Isolde Palombo; Daniel Daley; Said Eshaghi; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; membrane proteins; assembly; cofactors; magnesium; Escherichia coli; Biochemistry; biokemi;

    Sammanfattning : Membrane proteins are key players in many biological processes. Since most membrane proteins are assembled into oligomeric complexes it is important to understand how they interact with each other. Unfortunately however, the assembly process (i.e. LÄS MER

  7. 5. Membrane-mimetic systems : Novel methods and results from studies of respiratory enzymes

    Författare :Gustav Nordlund; Peter Brzezinski; Joachim Heberle; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Lipids; membrane proteins; method development; respiration; reconstitution; supported membranes; SNAREs; liposome fusion; lipid-protein interactions; Biochemistry; biokemi;

    Sammanfattning : The processes localized to biological membranes are of great interest, both from a scientific and pharmaceutical point of view. Understanding aspects such as the detailed mechanism and regulation of these processes requires investigation of the structure and function of the membrane-bound proteins in which they take place.
