    Sammanfattning : The neuropeptide Y (NPY) system consists of 3-4 peptides and 4-7 receptors in vertebrates. It has powerful effects on appetite regulation and is involved in many other biological processes including blood pressure regulation, bone formation and anxiety. LÄS MER

  2. 2. Prediction of zinc-binding sites in proteins and efficient protein structure description and comparison

    Sammanfattning : A large number of proteins require certain metals to stabilize their structures or to function properly. About one third of all proteins in the Protein Data Bank (PDB) contain metals and it is estimated that approximately the same proportion of all proteins are metalloproteins. LÄS MER

  3. 3. How could Christmas trees remain evergreen? : photosynthetic acclimation of Scots pine and Norway spruce needles during winter

    Författare :Pushan Bag; Stefan Jansson; Fransis Andre Wollman; Umeå universitet; []

    Sammanfattning : Plants and other green organisms harvest sunlight by green chlorophyll pigments and covertit to chemical energy (sugars) and oxygen in a process called photosynthesis providing the foundation for life on Earth. Although it is unanimously believed that oceanic phytoplanktons are the main contributors to the global photosynthesis, the contribution of coniferous boreal forests distributed across vast regions of the northern hemisphere cannot be undermined.

  4. 4. On the crystallization of membrane proteins in lipidic sponge and cubic phases

    Författare :Pia Jeanette Hindrichsen; Chalmers tekniska högskola; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; monoolein MO ; selachyl alcohol; cubic phase; sponge phase; small angle X-ray scattering; protein crystallization; phytantriol PT ;

    Sammanfattning : Membrane proteins are involved in many important biological processes and in order to understand their mechanism, their three-dimensional structures need to be elucidated to high resolution by for example X-ray crystallography. However, there is only limited structural knowledge for membrane proteins which is partly explained by the difficulties in obtaining well-diffracting crystals. LÄS MER

  5. 5. Unveiling Mechanistic Details of Macromolecular Interactions: Structural Design and Molecular Modelling of DNA-Protein Systems in Their Active State

    Sammanfattning : Molecular structure is fundamental for understanding mechanisms of molecular interactions. This applies not least to understanding biological function: every biological cell, whether bacterial or human, is an immensely complex system of thousands of molecules that exist in constant motion and interaction with each other.
