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

    Författare :Gustav Nordlund; Peter Brzezinski; Joachim Heberle; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; 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.

  2. 2. Choreography of a proton pump : Studies of charge-transfer reactions in cytochrome c oxidase

    Författare :Jóhanna Vilhjálmsdóttir; Peter Brzezinski; Joachim Heberle; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; heme-copper oxidase; cytochrome c oxidase; respiration; proton pump; electron transfer; proton transfer; proton-transfer pathway; midpoint potential; proton-pumping mechanism; Biochemistry; biokemi;

    Sammanfattning : In the last step of cellular respiration, electrons from metabolites are transferred to molecular oxygen, mediated by the enzyme complexes of the respiratory chain. Some of these enzyme complexes couple these redox reactions to formation of an electrochemical proton gradient across the cell membrane. The proton gradient is used e.g. LÄS MER
