  1. 1. Iron in Haem Biosynthesis. Structural Studies of Ferrochelatase and Frataxin

    Författare :Tobias Karlberg; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Naturvetenskap; Natural science; Molekylär biofysik; Molecular biophysics; Biomedicinska vetenskaper; Biomedical sciences; protein crystallography; ferrochelatase; haem biosynthesis; iron; frataxin;

    Sammanfattning : Ferrochelatase catalyses the synthesis of heme by inserting Fe(II) into protoporphyrin IX. The structure of ferrochelatase from yeast has been determined (2.4 Å). The structure is homodimeric with each of the monomer made up of two Rossmann type domains with an active-site cleft between them. LÄS MER

  3. 2. Separation of Proteins with Capillary Electrophoresis in Coated Capillaries with and without Electroosmosis : Studies on Zone Broadening and Analytical Performances

    Författare :Sheila Mohabbati; Douglas Westerlund; Bo Karlberg; Uppsala universitet; []
    Nyckelord :Pharmaceutical chemistry; Capillary electrophoresis; capillary coatings; proteins; zone broadening; zone sharpening; efficiency; resolution; protein-surface adsorption; protein-buffer interaction; analytical performance; Farmaceutisk kemi;

    Sammanfattning : Proteins have such structural features that they may interact with different types of surfaces by all possible forces, i.e., electrostatic, hydrogen bonding, hydrophobic. In this thesis two different types of coatings for fused silica capillaries aimed to eliminate such interactions have been studied. LÄS MER
