  1. 1. On the antiporter-like subunits of respiratory chain Complex I - implications for the evolution and coupling mechanism of the NADH:quinone oxidoreductase enzyme complex

    Author : Cecilie Mathiesen; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Metabolism; Biokemi; metabolism; Biochemistry; mrp; electron transport; respiration; membrane protein;

    Abstract : Complex I or NADH:quinone oxidoreductase is the largest enzyme complex, but the least understood energy coupling site in the respiratory chain of mitochondria and bacteria. No high-resolution structural information exists for this enzyme and the molecular mechanism that couples electron transfer and proton pumping is not understood. READ MORE

  2. 2. Painfully Energetic : A tale of two proteins potentially connected

    Author : Eva Sperling; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Complex I; Mrp-antiporter; Membrane bound hydrogenases; TRP ion channels; TRPA1; thermosensation; chemosensation; 23Na-NMR;

    Abstract : NADH:quinone oxidoreductase (Complex I) is the first enzyme of the respiratory chain and is involved in energy conservation generating an electro-chemical gradient across a membrane. The enzyme can be divided into a membrane spanning domain and a hydrophilic domain, which protrudes from the membrane. READ MORE

  3. 3. The evolution of respiratory chain complex I from smaller functional modules

    Author : Vamsi Moparthi; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Hyf; Hyc; Membrane bound hydrogenases; NADH:quinone oxidoreductase; Mrp antiporter; 16S rRNA;

    Abstract : NADH:quinone oxidoreductase, or complex I, is a large membrane bound enzyme in the respiratory chain of living organisms, that has evolved from the combination of smaller functional building blocks. The enzyme has a conserved core structure, comprising 14 protein subunits: Seven subunits protrude from the membrane and contain a flavin and eight iron-sulfur clusters. READ MORE

  4. 4. Antiporter-like protein subunits of respiratory chain complex I

    Author : Kamil Gorecki; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Complex I is the mitochondrial enzyme complex that oxidizes NADH produced in the citric acid cycle and reduces quinone in the membrane, coupled to proton pumping out of the mitochondrial matrix, creating a membrane potential. This process generates about 40% of the energy used by living organisms. READ MORE
