  1. 1. NMR Investigations of Peptide-Membrane Interactions, Modulation of Peptide-Lipid Interaction as a Switch in Signaling across the Lipid Bilayer

    Author : Sofia Unnerståle; Lena Mäler; Göran Widmalm; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; peptide-lipid interaction; membrane mimetic; NMR; biophysics; Molecular biophysics; Molekylär biofysik; biofysik; Biophysics;

    Abstract : The complexity of multi cellular organisms demands systems that facilitate communicationbetween cells. The neurons in our brains for instance are specialized in this cell-cellcommunication. READ MORE

  2. 2. Modeling and Data Analysis in Cellular Biophysics

    Author : Jacob Kowalewski; Hjalmar Brismar; Anita Aperia; Björn Önfelt; Karl-Eric Magnusson; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Biophysics; Biofysik;

    Abstract : Cellular biophysics deals with the physical aspects of cell biology. This thesis presents a number of studies where mathematical models and data analysis can increase our understanding of this field. READ MORE

    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
