  1. 11. Enzyme selectivity as a tool in analytical chemistry

    Författare :Anders Hamberg; Karl Hult; Harry Brumer; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; substrate specificity; competing substrates; enantiomeric excess analysis; library screening; ladder sequencing; carboxypeptidase Y; 2-pyridylmethylamine; MALDI; Candia antarctica lipase B; pig liver esterase; horse liver alcohol dehydrogenase; acylated cyanohydrins; Biochemistry; Biokemi;

    Sammanfattning : Enzymes are useful tools as specific analytical reagents. Two different analysis methods were developed for use in the separate fields of protein science and organic synthesis. Both methods rely on the substrate specificity of enzymes. Enzyme catalysis and substrate specificity is described and put in context with each of the two developed methods. LÄS MER

  3. 12. HYDROPHOBIC PEPTIDE TAGS - As tools in bioseparation and investigation of recombinant proteins

    Författare :Sara Fexby; Tillämpad biokemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; E. coli; Biochemical technology; Biokemisk teknik; fusion protein; tyrosine; hydrophobicity; Hydrophobic interaction chromatography; aqueous two-phase system;

    Sammanfattning : This thesis describes the possibility of using hydrophobic peptide tags as tools for bioseparation and for the investigation of recombinant proteins. The hydrophobicity of a protein can easily be changed by minor modifications, such as fusions of tyrosine-containing peptides. LÄS MER

  4. 13. Molecular basis and pharmacological implications of Alzheimer amyloid ß-peptide fibril formation

    Författare :Lars Tjernberg; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Alzheimer s disease; amyloid; fibrils; inhibitor; protease resistance; electron microscopy; fluorescence correlation spectroscopy.;

    Sammanfattning : Alzheimer's disease is a progressive neurodegenerative disease, mostly affecting elderly. The invariable deposition of protease-resistant fibrils of Alzheimer amyloid ß-peptide (Aß) in the parenchyma and blood vessels of the brain is a central event. LÄS MER

  5. 14. Unravelling protein stability and aggregation

    Författare :Tanja Weiffert; NanoLund: Centre for Nanoscience; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; protein stability; protein aggregation; amyloid beta peptide; protein stabilization; split GFP; monellin; secretagogin; ; aggregation kinetics; toxicity; aggregation mechanism; coaggregation;

    Sammanfattning : Proteins are complex macromolecules that are fundamental to all living species. The stability of proteins are governed by non-covalent forces within the protein and between the protein and its surrounding environment. LÄS MER

  7. 15. Affibody molecules for proteomic and therapeutic applications

    Författare :Caroline Grönwall; Stefan Ståhl; Lena Jendeberg; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Affibody; protein engineering; phage display; amyloid beta peptide; transferrin; CD25; IL-2 receptor; proteomics; Bioengineering; Bioteknik;

    Sammanfattning : This thesis describes generation and characterization of Affibody molecules with future applications in proteomics research, protein structure determinations, therapeutic treatment of disease and medical imaging for in vivo diagnostics. Affibody molecules are engineered affinity proteins developed by combinatorial protein engineering from the 58-residue protein A-derived Z domain scaffold. LÄS MER
