1. 6. Computational Analysis of Molecular Recognition Involving the Ribosome and a Voltage Gated K+ Channel

   Författare :Martin Andér; Johan Åqvist; Lennart Nilsson; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; computer simulations; molecular dynamics; ligand binding; binding free energy; linear interaction energy; codon recognition; translation termination; release factor; voltage gated potassium ion channel; Kv1.5; Structural biology; Strukturbiologi; Biochemistry; Biokemi; Biokemi; Biochemistry;

   Sammanfattning : Over the last few decades, computer simulation techniques have been established as an essential tool for understanding biochemical processes. This thesis deals mainly with the application of free energy calculations to ribosomal complexes and a cardiac ion channel. LÄS MER

3. 7. Fighting Tuberculosis – : Structural Studies of Three Mycobacterial Proteins

   Författare :Alina Castell; Torsten Unge; Manfred Weiss; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mycobacterium tuberculosis; Rv0216; Rv0130; Mycobacterium smegmatis; branched chain aminotransferase; X-ray crystallography; fatty acid metabolism; Structural biology; Strukturbiologi;

   Sammanfattning : This thesis presents the cloning, purification, crystallization, and structural studies of two unknown proteins from Mycobacterium tuberculosis, and of an aminotransferase from Mycobacterium smegmatis. Structural knowledge of these proteins is of highest interest for structure-based drug design, which is one of the approaches that can be used in order to fight tuberculosis (TB). LÄS MER

4. 8. Tunnels and Grooves : Structure-Function Studies in Two Disparate Enzymes

   Författare :Daniel Ericsson; Sherry Mowbray; Guy Dodson; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mycobacterium tuberculosis; ribonucleotide reductase; peptide inhibitors; fluorescence polarization; lipase; interfacial activation; hydrolase; X-ray structure; substrate specificity; Structural biology; Strukturbiologi;

   Sammanfattning : This thesis describes structural and binding studies in enzymes from two different  organisms: ribonucleotide reductase from Mycobacterium tuberculosis (RNR) and lipase A from Candida antarctica (CalA).RNR is viable as a target for new drugs against the causative agent of tuberculosis.

5. 9. Structural studies of the surface adhesin SspB from Streptococcus gordonii

   Författare :Nina Forsgren; Karina Persson; Inger Andersson; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Streptococcus gordonii; X-ray crystallography; surface adhesin; dental plaque; structural biology; Structural biology; Strukturbiologi; ODONTOLOGY; ODONTOLOGI; odontologi; Odontology;

   Sammanfattning : Surface proteins on microorganisms that build up the oral biofilm are key players in the formation of the biofilm. Antigen I/II proteins are surface adhesins found on virtually all oral streptococci and share a conserved multi-domain architecture. These adhesins bind surface components on other bacteria and on host cells. LÄS MER

7. 10. Structural and functional properties of transthyretin

   Författare :Anders Karlsson; A. Elisabeth Sauer-Eriksson; Salam Al-Karadaghi; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Transthyretin; Amyloidosis; X-ray crystallography; Protein structure; Protein; Structural biology; Strukturbiologi;

   Sammanfattning : The hereditary transthyretin (TTR) amyloidoses are rare, and in severe cases, fatal disorders caused by mutations in the TTR gene. The clinical picture is diverse, involving neuropathies and myopathies, and mainly depends on the causative mutation and the sites and rates of amyloid deposition. LÄS MER
