1. Structural and functional studies of biomolecules with NMR and CD spectroscopy
Sammanfattning : Experimentally derived biomolecular structures were determined by Nuclear Magnetic Resonance (NMR). The properties of selected peptides and proteins in solution and in membrane mimicking micelles were observed by circular Dichroism (CD), mass spectrometry (MS), and other spectroscopic techniques.

2. Interactions of satellite phage P4 with its helpers : P2 and WΦ phages
Sammanfattning : Bacteriophage P4 is a defective phage that needs a helper phage to grow lytically, since it lacks structural genes and genes encoding host cell lysis functions. P4 has the capacity to derepress the unrelated prophage P2, or its relatives after infection, thereby getting access to the late functions of the helper. LÄS MER
3. Molecular Studies of Three Coliphage Repressor Proteins P2 C, P2 Hy dis C and Wphi C : Kinetics, Oligomeric States and Structural Studies
Sammanfattning : P2, P2 Hy dis and WΦ are heteroimmune and closely related E. coli phages that can either grow lytically or form lysogeny after infection. The developmental switch region that contains two divergent promoters, the early Pe and the lysogenic Pc promoter, and two repressors, controls the life mode of the phage. LÄS MER
4. Structural Studies of Flexible Biomolecules and a DNA-binding Protein
Sammanfattning : The knowledge of the three-dimensional structures of proteins and polypeptides is essential to understand their functions. The work shown in this thesis has two objectives. LÄS MER
5. Developmental switches in a family of temperate phages
Sammanfattning : P2 is the prototype phage of the non-lambdoid P2 family of temperate phages. A developmental switch determines whether a temperate phage will grow lytically or form lysogeny after infection. P2 related phages have two face-to-face located promoters controlling the lysogenic and the lytic operon respectively, and two repressors. LÄS MER
