1. Viral Loop Dynamics in Temperate and Polar Freshwaters
Sammanfattning : All cellular organisms in aquatic environments are susceptible to virus attack. Viruses are the smallest but most abundant biological entities in freshwaters. This thesis describes interactions between viruses and bacteria in temperate and polar freshwaters with particular emphasis on Arctic and Antarctic aquatic systems. LÄS MER
2. A Genetic Switch in Bacteriophages within the Peduovirinae Subfamily : Structure, Function and Evolution
Sammanfattning : The temperate bacteriophages in the Peduovirinae subfamily can either grow lytically or integrate into their bacterial host and form lysogeny. Which one of the two life cycles the phage will enter after infection is controlled by a transcriptional switch. LÄS MER
3. Structure-Function Studies of Bacteriophage P2 Integrase and Cox protein
Sammanfattning : Probably no group of organisms has been as important as bacteriophages when it comes to the understanding of fundamental biological processes like transcriptional control, DNA replication, site-specific recombination, e.t.c.The work presented in this thesis is a contribution towards the complete understanding of these organisms.

4. 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
5. Structural and biochemical studies of phage P2 DNA-binding proteins and human tetraspanins
Sammanfattning : Biochemical studies of proteins are crucial for a more detailed view of the world around us. The focus of biochemical studies can vary, from a complex mammalian system to a more simple viral entity, but the same methods and principles apply. In biochemistry one rely on both in vitro and in vivo analyses to understand biological processes. LÄS MER
