  1. 1. Structural studies on the integral membrane protein, ubiquinol oxidase from Escherichia coli

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Jeff Abramson; Uppsala universitet.; [2001]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; crystal structure; ubiquinol oxidase; membrane protein; oxidases; Biokemi; NATURAL SCIENCES Chemistry Biochemistry; NATURVETENSKAP Kemi Biokemi; biokemi; Biochemistry;

    Abstract : Heme-copper oxidases are redox-driven proton pumps that couple the reduction of molecular oxygen to water with the vectorial translocation of protons across the membrane. The proton gradient generated by heme-copper oxidases and the other members of the aerobic respiratory chain is ultimately used to drive the synthesis of ATP. READ MORE

  2. 2. Structure and function of the presynaptically neurotoxic phospholipase A² from the Australian tiger snake - Notechis scutatus scutatus

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Bengt Westerlund; Uppsala universitet.; [1997]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Biokemi; NATURAL SCIENCES Chemistry Biochemistry; NATURVETENSKAP Kemi Biokemi; biokemi; Biochemistry;

    Abstract : Notexin is a member of the phospholipase A2, (PLA2) family of proteins. Despitethe fact they are homologous proteins with similar sequence and almost identicalstructures, they show an impressing diversity of functions. READ MORE

  3. 3. New approaches in biomembrane chromatomatography and microchromatographic techniques

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Cheng-Ming Zeng; Uppsala universitet.; [1998]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Biokemi; NATURAL SCIENCES Chemistry Biochemistry; NATURVETENSKAP Kemi Biokemi; biokemi; Biochemistry;

    Abstract : Development of methods for rendering chromatography more applicable to studies in lifesciences remains an area of active research. In the present work, new methods inbiomembrane chromatography and microchromatographic techniques have been developedand applied successfully to quantitative analysis of biological interactions and separations ofproteins on a micro-scale.

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

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Yanxiao Zhang; Uppsala universitet.; [1997]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Biokemi; NATURAL SCIENCES Chemistry Biochemistry; NATURVETENSKAP Kemi 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.

  5. 5. Partition chromatography of drugs on immobilized liposomes and biomembranes : A method applicable to screening in drug design

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Farideh Beigi; [2000]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Biokemi; NATURAL SCIENCES Chemistry Biochemistry; NATURVETENSKAP Kemi Biokemi; biokemi; Biochemistry;

    Abstract : One of the main pathways for drug passage into cells is diffusion across the lipid bilayer ofthe cell membrane. A key factor in this process is the drug partitioning into the bilayer, whichcan be translated into a retention in a chromatographic system. READ MORE
