   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Moraxella IgD binding protein; adhesin; leukotriene A4 hydrolase; small angle x-ray scattering; crystallography; circular dichroism;

   Sammanfattning : Protein molecules are responsible for many biological functions in cells. In order to fulfill their various biological roles, these chain-like molecules must fold into precise three-dimensional shapes. The knowledge of accurate molecular structures is a prerequisite for rational drug design and for structure based functional studies. LÄS MER

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

   Författare :Pia Jeanette Hindrichsen; Chalmers tekniska högskola; []

   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
