    Sammanfattning : Structural studies of large biological assemblies pose a unique problem due to their size, complexity and heterogeneity. Conventional methods like x-ray crystallography, NMR, etc. are limited in their ability to address these issues. To overcome some of these limitations, single particle methods were used. LÄS MER

  3. 2. Molecular Studies of Three Coliphage Repressor Proteins P2 C, P2 Hy dis C and Wphi C : Kinetics, Oligomeric States and Structural Studies

    Författare :Petri Henriksson Peltola; Elisabeth Haggård-Ljungquist; Sankar Adhya; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; molekylärgenetik; Molecular Genetics;

    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. 3. Site-Specific Recombination : Integrases, Accessory Factors and DNA Targets of P2-like Coliphages

    Författare :Lina Sylwan; Elisabeth Haggård-Ljungquist; Margaret C. M. Smith; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Genetics; Genetik; molekylärgenetik; Molecular Genetics;

    Sammanfattning : The temperate coliphage P2 and its family members integrate their genomes into the host Escherichia coli chromosome by a site-specific recombination mechanism to form lysogeny. Integration takes place between the complex phage attP site and the simple bacterial attB site and is catalyzed by the phage encoded integrase (Int). LÄS MER
