1. Structural Studies of Bacteriophage PRR1 and HIV-1 protease
Abstract : Viruses are a diverse genera of organisms adapted to thrive in many different hosts from prokaryotic to eukaryotic.We present here the structure of bacteriophage PRR1 virus-like particle (VLP), belonging to Leviviridae family. Our structure reveals calcium ions in the VLP. READ MORE

2. Control of Quasi-Equivalence in Virus Capsids
Abstract : 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. READ MORE

3. Engineering of Antibacterial Phage-Derived Proteins
Abstract : The increasing threat of antibiotic resistance calls for the development of new treatment methods. Bacteriophages are interesting candidates since they can lyse bacteria with great efficiency. Bacteriophages produce enzymes called endolysins which break down the peptidoglycan in the cell wall at the end of the infection cycle. READ MORE

4. Structure-Function Studies of Bacteriophage P2 Integrase and Cox protein
Abstract : 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.

5. 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
