    Sammanfattning : Ribonucleotide reductase (RNR) is the enzyme responsible for de novo synthesis of deoxyribonucleotides, needed for both synthesis and repair of cellular DNA. The RNRs known so far are divided into three distinct classes; I, II and III. The conventional class I enzyme is composed of two separate subunits. LÄS MER

  5. 5. Biophysical studies of cell-penetrating peptides and of the RNR inhibitor Sml1

    Detta är en avhandling från Stockholm : Institutionen för biokemi och biofysik

    Författare :Elsa Bárány-Wallje; Stockholms universitet.; [2008]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cell-penetrating peptides; transportan; bicelles; Sml1; TECHNOLOGY Engineering physics Biophysics; TEKNIKVETENSKAP Teknisk fysik Biofysik; Biophysics; biofysik;

    Sammanfattning : Several short peptides, so called cell-penetrating peptides, have the capability to transport large hydrophilic cargos through the cell membrane. The objective is to use these peptides as drug carriers and thereby enhance the uptake of drugs into cells.Three different cell-penetrating peptides are characterized in this thesis. LÄS MER
