Unraveling the Intricate Architecture of Human Mitochondrial Presequence Translocase - Insights on its Evolution and Role in Tumourigenesis
(2018-04-23)
The present thesis focuses on the elucidation of human mitochondrial inner membrane presequence-translocation machinery with implications on cancer cell proliferation. Mitochondria are the endosymbiotic organelles in an ...
The Role of Nursery Size and Plant Phenology on the Reproduction of and Relationships within a Fig-fig Wasp Nursery Pollination System
(2018-05-09)
Obligate nursery pollination mutualisms such as the fig–fig wasp system, with their central plant–pollinator mutualism associated with non-pollinating satellite wasp species, can function as closed system microcosms ...
Studies on exosomal microRNAs and proteins associated with Hepatitis C and Dengue virus induced pathogenesis
Studies on the exosomal microRNAs and proteins associated with Hepatitis C and Dengue virus-induced pathogenesis.
Hepatitis C virus and Dengue virus are the group of positive-strand RNA viruses belonging to the family ...
Structural and functional insights of biological macromolecules associated with infectious diseases – single particle cryo-electron microscopy based studies
In the global context, particularly in India, the two most important infectious diseases among many others are Tuberculosis (TB), an age-old disease and COVID-19, a new-age disease. This thesis focuses on some of the key ...
Immunological consequences of host signaling-regulated epigenetic modification(s) during mycobacterial pathogenesis
Introduction: Mycobacterium tuberculosis (Mtb), the principal etiological agent of pulmonary tuberculosis (TB), continues to co-evolve with the human population making itself one of the most potent infectious killer in the ...
Roles of Protein Acetylation in the Human Pathogen Helicobacter pylori
Helicobacter pylori is a gram-negative epsilon proteobacterium infecting half of the world population. H. pylori is a naturally competent bacterium with a huge repertoire of Restriction-Modification (RM) systems. The ...
Structural, mechanistic and pharmacological studies of inhibitory neurotransmitter transporters
Gamma-aminobutyric acid (GABA) is the major inhibitory neurotransmitter in the central nervous system (CNS). The synaptic levels of GABA are controlled by the activity of GABA transporters (GATs) present in the presynaptic ...
Characterization of the transsulfuration enzyme Cystathionine beta-synthase as a novel regulatory node in the sulfur metabolism of Mycobacterium tuberculosis
Methionine and cysteine metabolisms are important for the survival and pathogenesis of Mycobacterium tuberculosis (Mtb). The transsulfuration pathway converts methionine to cysteine and represents an important link between ...
Structural and Biophysical studies to evaluate the influence of oligomerization on biomolecular function
Oligomeric proteins are more common than monomers. This aspect of molecular evolution substantially contributes to functional diversity and the acquisition of features such as cooperativity and regulatory mechanisms. Not ...
Understanding the Functions of Nucleoid Associated Proteins in Mycobacterium tuberculosis
The prokaryotic genome, though lacks a membrane bound organelle for its housing, is restricted to only about 25% of the cytoplasmic space called the nucleoid. The dramatic compaction required for the genome to fit in is ...
