  1. 16. Cell wall chemotyping for functional genomics : applications of pyrolysis-gas chromatography / mass spectrometry

    Författare :Lorenz Gerber; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The interest in lignocellulose as a sustainable resource for energy and materials has fueled research on biotechnology applications in tree breeding to improve biomass production and wood properties. An important aspect of this research is the basic understanding of gene function in wood formation, where analysis of wood chemistry and wood structure is of utmost importance. LÄS MER

  3. 17. The Design and Structure Prediction of Protein Oligomers

    Författare :Robert Lizatovic; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; virus capsids; coiled coils; molecular replacement; symmetry; Rosetta; protein design; structure prediction;

    Sammanfattning : The minimum free energy state of a protein (the native state) is encoded by its amino-acid sequence. Due to the many torsional degrees of freedom (DOF) available to a polypeptide chain, a vast number of conformations is possible. LÄS MER

  4. 18. In silico protein design for the enhancement of protein stability and function

    Författare :David A. Hueting; Per-Olof Syrén; Hjalmar Brismar; Zbynek Prokop; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Protein Engineering; Ancestral sequence reconstruction; terpene cyclases; SARS-CoV-2; Spike protein; PET; PETase; rational engineering; Proteinteknik; Förfäders sekvensrekonstruktion; Terpencyklas; SARS-CoV-2; Spike protein; PET; PETas; rationell proteinteknik; Kemi; Chemistry;

    Sammanfattning : Enzymes are natures catalysts that increase the rate of a chemical reaction. The increased rate of a reaction is required to be able to sustain life. Despite the huge impact of enzymes, they are not perfect catalysts. LÄS MER

  5. 19. Protein and polyelectrolyte layer-by-layer films: Assembly and electron transfer

    Författare :Karolina Haberska; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; layer-by-layer assembly; nanoparticles; electron transfer; bioelectrocatalysis;

    Sammanfattning : A layer-by-layer deposition technique for assembly of the three-dimensional bioelectrochemical systems, with potential applications such as sensing layers in biosensors or catalytic organisations in biofuel cells, was addressed in this thesis. Several investigations were carried out to understand and control multilayer films formation on planar surfaces, using electrochemical and ellipsometrical methods. LÄS MER

  7. 20. Hydrophobic Fusion Tags: Implications For Bioseparation and Cellular Expression

    Författare :Anna Collén; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; protein production; secretion; aqueous two-phase systems; Trichoderma reesei; endoglucanase; Biochemistry; Metabolism; Biokemi; metabolism;

    Sammanfattning : The studies in this thesis have shown that the partitioning of endoglucanase I (EGI, Cel7B) from T. reesei could be significantly improved by relatively minor genetic engineering. By adding short peptides composed of tryptophan and proline residues to EGI, extreme partitioning could be obtained. LÄS MER
