1. Structural studies of proteins in apoptosis and lipid signaling
Sammanfattning : Signaling pathways control the fate of the cell. For example, they promote cell survival or commit the cell to death (apoptosis) in response to cell injury or developmental stimuli, decisions, which are vital for the proper development and functioning of metazoan. LÄS MER
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. Of spiders, bugs, and men : Structural and functional studies of proteins involved in assembly
Sammanfattning : Protein assembly enables complex machineries while being economical with genetic information. However, protein assembly also constitutes a potential threat to the host, and needs to be carefully regulated.Sulfate is a common source of sulfur for cysteine synthesis in bacteria. LÄS MER
4. Antibiotic Resistance and the Cellular Currency S-adenosyl-methionine : Modification of aminoglycosides and nucleic acids
Sammanfattning : Streptomycin and spectinomycin are antibiotics that bind to ribosomes and inhibit protein synthesis. Common resistance mechanisms involve enzymatic modification of the two drugs by aminoglycoside nucleotidyltransferases (ANTs). The first part of this thesis covers the structural mechanism of two ANT enzymes. LÄS MER
5. Structural and Biochemical Characterizations of Three Potential Drug Targets from Pathogens
Sammanfattning : As antibiotic resistance of various pathogens emerged globally, the need for new effective drugs with novel modes of action became urgent. In this thesis, we focus on infectious diseases, e.g. LÄS MER
