1. 1. Properties of Protein and Polymer Systems

   Författare :Fredrik Carlsson; Avdelningen för Konstruktionsteknik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fysikalisk kemi; Physical chemistry; lysozyme; mica; surface; dimerization; precipitation; aggregate; cluster; complex; polyelectrolyte; protein; polymer;

   Sammanfattning : Interactions of proteins with other proteins, with polymers and with surfaces are of great practical importance within for instance protein purification, drug delivery, and food technology. The aim of this work is to increase the understanding of protein-protein, protein-polyelectrolyte, and protein-surface interactions, particularly concerning the role of electrostatic interactions in these systems.

3. 2. Human Aquaporins: Production, Characterization and Interactions

   Författare :Jennie Sjöhamn; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; aquaporins; membrane protein; protein production; protein characterization; protein:protein interactions; structural biochemistry;

   Sammanfattning : Membrane proteins are essential components of the cell and responsible for the communication with the outside environment and transport of molecules across the membrane. Water transport is facilitated by aquaporins, which are water selective transmembrane pores that serve to maintain cell homeostasis. LÄS MER

4. 3. Structural and functional studies of a novel Botulinum neurotoxin and of MTH1

   Författare :Linda Henriksson; Pål Stenmark; Maria Selmer; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Botulinum neurotoxin; botulism; cancer; gene cluster; molecular structures; MTH1; NTNH; oxidised nucleotides; progenitor complex; protein expression; protein purification; X-ray crystallography; Biochemistry; biokemi;

   Sammanfattning : X-ray crystallography visualizes the three dimensional molecular structures of proteins at atomic resolution. Seeing the molecular structure of a biomedically interesting protein enables a higher understanding of its function. LÄS MER

5. 4. The Membrane-Spanning Domain of Complex I Investigated with Fusion Protein Techniques

   Författare :Maria Trane; Biokemi och Strukturbiologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NuoN; NuoM; NuoL; covalent bound heme; Bacillus subtilis; Escherichia coli; membrane protein; His-tag; Cytochrome c; NADH:quinone oxidureductase; fusion protein;

   Sammanfattning : NADH:quinone oxidoreductase, or complex I, is a large, complex and poorly understood bioenergetic enzyme in the respiratory chain of living organisms. The enzyme has a conserved core structure, comprising fourteen protein subunits: Seven subunits protrude from the membrane and contain a flavin prosthetic group and eight iron-sulfur clusters that guide electrons from the oxidation of NADH towards the quinone binding site(s).

7. 5. Bax and oxidized phospholipids - a deadly complex : Apoptotic protein-lipid assemblies studied by MAS NMR spectroscopy

   Författare :Artur Dingeldein; Gerhard Gröbner; Mikael Elofsson; Tobias Sparrman; Daniel Topgaard; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NMR spectroscopy; mitochondrial membranes; apoptosis; membrane dynamics and organization; Bcl-2 family proteins; Bax protein; biokemi; Biochemistry;

   Sammanfattning : Mitochondria are renowned for their vital role as cellular powerhouses because they provide ATP via cellular respiration. Additionally, these organelles also play an important role in other physiological processes, such as apoptosis. LÄS MER
