  1. 1. 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

  3. 2. Prokaryotic respiratory supercomplexes : Studies of interactions between complexes III and IV

    Författare :Olga Stah; Pia Ädelroth; Petra Hellwig; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; bioenergetics; membrane protein; bacterial respiration; electron transport chain; supercomplex; cytochrome c oxidase; membrane-anchored cytochrome c; cytochrome bc1 complex; electron transfer; proton transfer; time-resolved spectroscopy; apoptosis; biokemi; Biochemistry;

    Sammanfattning : Respiratory processes for cellular energy conversion are carried out by the membrane-associated enzymes of the electron transfer chain (ETC). In recent years there has been emerging data showing that the members of the ETC organize into higher-level assemblies called supercomplexes (SCs) whose functional relevance is not yet fully understood.
