1. Structural Studies of Large dsDNA Viruses using Single Particle Methods
Abstract : 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. READ MORE

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

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