1. Structural studies of polychlorinated hydrocarbons : DDT analogues and degradation products
Sammanfattning : The crystal structures of five analogues and degradation products of DOT have been determined by single crystal X-ray diffraction techniques. The conformations of these compounds are discussed and compared with the other DDT-type compounds whose crystal structures have been solved. LÄS MER
2. Structural modeling of membrane transporter proteins
Sammanfattning : A fundamental process of all living organisms - the transport of molecules across cellular membranes through membrane transport proteins - is investigated.After a brief review of general properties of biological membranes follows a recollection of the major methods of membrane transport that Nature utilizes (Chapter 1). LÄS MER
3. The use of evolutionary information in protein alignments and homology identification
Sammanfattning : For the vast majority of proteins no experimental information about the three-dimensional structure is known, but only its sequence. Therefore, the easiest way to obtain some understanding of the structure and function of these proteins is by relating them to well studied proteins. This can be done by searching for homologous proteins. LÄS MER
4. Exploiting reciprocal space : Electron diffraction, textures and precession
Sammanfattning : Electron crystallography emerges as a new tool for accurate structure determination of very small crystals. In order to exploit the full potential of electron diffraction, the methods for data acquisition and processing have to be developed towards the high standards of X-ray crystallography. LÄS MER
5. 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
