  4. 4. Biophysical investigations of ribonucleotide reductase : Activation and inhibition mechanisms

    University dissertation from Stockholm : Department of Biochemistry and Biophysics, Stockholm University

    Author : Maria Öhrström; Stockholms universitet.; [2010]

    Abstract : 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. READ MORE

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

    University dissertation from Stockholm : Institutionen för biokemi och biofysik

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

    Abstract : 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. READ MORE
