    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; water activity; sub-zero temperatures; enantioselectivity; peptide yields; asymmetric reductions of ketones; peptide synthesis; ADH from Thermoanaerobium brockii; subtilisin; Enzyme catalysis; a-chymotrypsin; organic solvent; aqueous media; Biotechnology; Bioteknik;

    Sammanfattning : The influence of different reaction parameters on enzyme selectivity was investigated. The reaction conditions studied were solvent dependence, water activity and reaction temperature. LÄS MER

  3. 2. Towards the Development of Photoswitchable β-Hairpin Mimetics

    Författare :Máté Erdélyi; Adolf Gogoll; Anders Karlén; John A. Robinson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organic chemistry; β-hairpin; peptidomimetics; Sonogashira; NMR; photochemistry; microwave; peptide; palladium; Organisk kemi; Organic chemistry; Organisk kemi;

    Sammanfattning : Peptide secondary structure mimetics are important tools in medicinal chemistry, as they provide analogues of endogeneous peptides with new physicochemical and pharmacological properties. The β-hairpin motif has been shown to be involved in numerous physiological processes, among others in regulation of eucariotic gene transcription. LÄS MER

  4. 3. Development of a novel methodology for the synthesis of oligonucleo-peptide conjugates

    Författare :Simone Zaramella; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Antisense; Oligonucleotide-peptide conjugates; Solid-phase synthesis; Histidine; Protecting groups.;

    Sammanfattning : Peptide-oligonucleotide conjugates constitute a new class of antisense molecules that exhibit improved biological activity over standard oligonucleotide analogues. Currently, these oligomeric bioconjugates are prepared by either solution- or solid-phase techniques. LÄS MER

  5. 4. Membrane and secretory protein production in Escherichia coli

    Författare :Alexandros Karyolaimos; Jan-Willem de Gier; Matthew DeLisa; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Escherichia coli; recombinant protein; tunable protein production; cytoplasmic membrane; periplasm; signal peptide; force profile analysis; co-translational folding; Biochemistry; biokemi;

    Sammanfattning : Escherichia coli (E. coli) is the most widely used bacterium for the production of recombinant proteins. However, the production of proteins in its cytoplasmic membrane or periplasm is challenging. Therefore, the aim of this doctoral thesis was to develop setups for enhancing the production of membrane and secretory proteins in E. LÄS MER

  7. 5. Rational and combinatorial genetic engineering approaches for improved recombinant protein production and purification

    Författare :Nina Bandmann; Per-Åke Nygren; Helena Berglund; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aqueous two-phase system; combinatorial library; expression vector; flow cytometry; fusion tag; partitioning; peptide library; phage display; recombinant proteins; ribosomal binding site; translation initiation; Bioengineering; Bioteknik;

    Sammanfattning : The bacterium Escherichia coli (E. coli) is in many situations an ideal host for production of recombinant proteins, since it generally provides a rapid and economical means to achieve sufficiently high product quantities. LÄS MER
