  2. 1. Regulation of proton-coupled electron transfer in cytochrome c oxidase : The role of membrane potential, proton pathways and ATP

    Author : Markus Björck; Peter Brzezinski; Thorsten Friedrich; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; cytochrome c oxidase; charge transfer; membrane potential; membrane protein; mitochondria; ATP; proton pump; Biochemistry; biokemi;

    Abstract : Cytochrome c oxidase (CytcO) is the final electron acceptor of the respiratory chain. In this chain a current of electrons, derived from degradation of nutrients, along with protons, are used to reduce oxygen to water. The reaction is exergonic and the excess energy is used to pump protons across the membrane. READ MORE

  4. 2. Characterization of ATP-dependent protein dynamics under native-like conditions

    Author : Harsha Ravishankar; Magnus Andersson; Hans Wolf-Watz; Lise Arleth; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; proteins; membrane proteins; structural dynamics; ATPases; MD simulations; X-ray scattering; FTIR spectroscopy; ATP; TR-XSS; structural biology.; Biochemistry; biokemi;

    Abstract : Proteins are biological macromolecules capable of accelerating biochemical reactions. To accomplish this, proteins undergo changes in their molecular structure. Advances in structural biology have resulted in ever-increasing numbers of high-resolution protein structures. READ MORE

  5. 3. ATP-Binding Cassette Efflux Transporters and Passive Membrane Permeability in Drug Absorption and Disposition

    Author : Pär Matsson; Per Artursson; Ulf Norinder; Peter Swaan; Uppsala universitet; []
    Keywords : Pharmaceutics; ATP-binding cassette; ABC transporter; P-gp; P-glycoprotein; ABCB1; BCRP; Breast cancer resistance protein; ABCG2; MRP2; Multidrug-resistance associated protein 2; ABCC2; Membrane permeability; Drug transport; Active transport; Passive diffusion; Multivariate data analysis; PLS; OPLS; QSAR; Galenisk farmaci;

    Abstract : Transport into and across the cells of the human body is a prerequisite for the pharmacological action of drugs. Passive membrane permeability and active transport mechanisms are major determinants of the intestinal absorption of drugs, as well as of the distribution to target tissues and the subsequent metabolism and excretion from the body.

  6. 4. Enterostatin - target proteins and intracellular mechanisms. Function in food intake and energy metabolism

    Author : Karin Berger; Molekylär endokrinologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ATP; energy metabolism; insulin; uncoupling protein; beta-casomorphin; opiate; SK-N-MC; INS-1; Medicin människa och djur ; Medicine human and vertebrates ; fat intake; F1F0-ATP synthase; appetite; enterostatin; satiety; obesity;

    Abstract : Hunger and satiety are the results of complex neural events that involve several neurotransmitters and peptides. Enterostatin is an appetite-regulating peptide released in the intestine in response to fat ingestion. Enterostatin specifically decreases fat intake, but has also metabolic effects like inhibition of insulin secretion. READ MORE
