  1. 21. Chromatographic studies of interactions between solutes, lipid bilayers and the glucose transporter Glut1

    Author : Yanxiao Zhang; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Biokemi; Biochemistry; Biokemi; biokemi; Biochemistry;

    Abstract : It is advantageous to analyze solute interactions with biological membranes by chromatography on stationary phases that mimic the membrane structures. In the present work, liposomes, proteoliposomes, human red cells and red cell membrane vesicles were immobilized for analyses ofinteractions between solutes (peptides, drugs, inhibitors and glucose), lipid bilayers and theglucose transporter Glut1.

    Abstract : Proteomics is the global analysis of proteins that covers a broad range of technologies aimed at determining the identity and quantity of proteins expressed in the cell, their three-dimensional structure and interaction partners. In contrast to genome, proteome reflects more accurately on the dynamic state of the cell, tissue, or an organism. READ MORE

  3. 23. PresequenceProtease (PreP), a novel Peptidasome in Mitochondria and Chloroplasts : Localization, Function, Structure and Mechanism of Proteolysis

    Author : Shashi Bhushan; Elzbieta Glaser; Johannes Herrmann; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Protein import; mitochondria; chloroplasts; PresequenceProtease; Alzheimer; Biochemistry; Biokemi; biokemi; Biochemistry;

    Abstract : The information for mitochondrial and chloroplastic protein import and targeting generally resides in the N-terminal part of the protein, called a targeting peptide. The targeting peptide is cleaved off by the organellar processing peptidases after import of a precursor protein. READ MORE

  4. 24. Integration and topology of membrane proteins

    Author : Carolina Boekel; Gunnar von Heijne; IngMarie Nilsson; Stephen High; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; insertion; Sec61; translocation; Biochemistry; Biokemi; biokemi; Biochemistry;

    Abstract : Membrane proteins comprise around 20-30% of most proteomes. They play important roles in most biochemical pathways. All receptors and ion channels are membrane proteins, which make them attractive targets for drug design. Membrane proteins insert and fold co-translationally into the endoplasmic reticular membrane of eukaryotic cells. READ MORE

  5. 25. Expression and structure-function characterisation of herpesviral proteins

    Author : Sue-Li Dahlroth; Pär Nordlund; Darren Hart; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Protein production; Herpesvirus; SOX; E. coli; Biochemistry; Biokemi; biokemi; Biochemistry;

    Abstract : In order to determine and study a protein structure, large amounts of it is needed. The easiest way to obtain a protein is to recombinantly overexpress it in the well-studied bacterium Escherichia coli. However, this expression host has one major disadvantage, overexpressed proteins might not be folded or be insoluble. READ MORE
