1. Exploring the Molecular Dynamics of Proteins and Viruses
Sammanfattning : Knowledge about structure and dynamics of the important biological macromolecules — proteins, nucleic acids, lipids and sugars — helps to understand their function. Atomic-resolution structures of macromolecules are routinely captured with X-ray crystallography and other techniques. LÄS MER
2. Ljungan Virus Replication in Cell Culture
Sammanfattning : Ljungan virus (LV) is a recently identified picornavirus of the genus Parechovirus. LV has been isolated from voles trapped in Sweden and also in the United States. LV infected small rodents may suffer from diabetes type 1 and type 2 like symptoms, myocarditis and encephalitis. LÄS MER
3. Control of Quasi-Equivalence in Virus Capsids
Sammanfattning : Many T=3 plant and insect viruses use a molecular switch in form of order/disorder of a segment of the polypeptide chain to regulate the quasi-equivalent contacts. The structure of a mutant of the T=3 capsid of bacteriophage fr confirms that this virus and other members of the Leviviridae family lack a switch mechanism. LÄS MER
4. The Design and Structure Prediction of Protein Oligomers
Sammanfattning : The minimum free energy state of a protein (the native state) is encoded by its amino-acid sequence. Due to the many torsional degrees of freedom (DOF) available to a polypeptide chain, a vast number of conformations is possible. LÄS MER
5. Structural Decorations in Viruses : Unraveling Acquired Functional Structures in Icosahedral RNA Virus Capsids
Sammanfattning : Viruses have a profound impact worldwide, posing challenges to animal welfare, agriculture, human health, and the ecosystem. This thesis examines the realm of non-enveloped icosahedral double-stranded (ds)RNA and single-stranded (ss)RNA viruses through three studies. LÄS MER
