Solution Structures and Dynamics of Conotoxins and Small MutS Related Domain from Helicobacter Pylori MutS2
(2018-06-08)The work presented in this thesis describes the determination of structures of peptides and proteins at atomic resolution. Nuclear Magnetic Resonance (NMR) spectroscopy was used as the principal method of investigation. ... -
Spatio-temporal Regulation of GPCR mediated MAPK Transactivation in Living Cells
Signal transduction is a mode of cellular communication essential for an organism’s sustenance and survival. Cell communication in higher organisms is largely executed by two classes of cell surface receptors i.e. G-protein ... -
Species Ranges, Richness and Replacement of Trees in the Evergreen Forests of the Western Ghats
(2018-05-14)It has been more than two centuries since the latitudinal pattern of increase in taxonomic richness from poles to equator was first documented. After two centuries of research, and with more than two dozen hypotheses ... -
Structural and Functional Analysis of Proteins involved in Microbial Stress Tolerance and Virulence
(2018-08-11)The genus Salmonella consists of pathogenic gram negative organisms which infect intestines of birds, animals and humans. They are the causative agents of salmonellosis which is characterised by diarrhoea, nausea, fever ... -
Structural and Functional Characterization of Enzymes of Proline Biosynthesis Pathway in Mycobacterium tuberculosis
Tuberculosis is the second largest killer disease on global scale after HIVAIDS. The rapid evolution of Mycobacterium tuberculosis into drug resistant strains and the toxicity of these drugs are the major constraints in ... -
Structural Feature of Prokaryotic Promoters and their Role in Gene Expression
(2018-05-14)Transcription initiation is an important step in the process of gene regulation in prokaryotes. Promoters are stretches of DNA sequence that are present in the upstream region of transcription start sites (TSSs), where RNA ... -
Structural Studies on SeMV Chimeras and TSV : Insights into Capsid Assembly
(2018-05-23)Assembly of virus capsid protein (CP) into icosahedrally symmetric particles is an intriguing and elegant process. In most cases of virus assembly, a large number of identical protein subunits self-assemble to generate a ... -
Structural Studies on the Intracellular Steps that Govern the Staphylococcus aureus Quorum Sensing System.
Quorum sensing in bacteria has been extensively examined over the past two decades. These studies suggest that the molecular mechanism that governs quorum sensing incorporates niche-specific, environmentally sensitive ... -
The Structure And Function Of The Vocal Repertoire Of The Greater Racket-Tailed Drongo (Dicrurus paradiseus) : Insights Into Avian Vocal Mimicry
(2017-07-12)Sound is used as a medium for communication by taxa as varied as insects, fish, amphibians, birds and mammals. In some birds like the suboscines, song is genetically encoded, whereas in parrots, hummingbirds and oscines, ... -
Structure Elucidation and Biological Evaluation of a Novel Steroidal Saponin, Cholestanol Glucoside Isolated from Saraca Asoca Enodophytic Fuungus, Lasiodiplodia Theobromae
(2018-05-16)Although the molecular mechanisms underlying the onset and progression of cancer has been unraveled to a great extend, cancer continues to remain a leading cause of death around the world. Clinical efficacy of the existing ... -
Studies on Regulation of Rat Corpus Luteum Function by Prolactin And Luteinizing Hormone
(2018-07-25)The corpus luteum (CL) is a transient endocrine structure formed from the remnants of an ovulated follicle with the primary purpose of producing progesterone (P4), a hormone vital for the establishment and maintenance of ... -
Substrate Specificity Determinants of Class III Nucleotide Cyclases
(2018-07-31)Cyclic AMP and cyclic GMP (cAMP and cGMP) are important second messengers in key signal-transduction pathways that mediate various physiological functions in bacteria and eukaryotes. Adenylyl Cyclases (ACs) and Guanylyl ... -
Systemic Profiling of Two Component Signaling Networks in Mycobacterium Tuberculosis
(2018-05-23)Mycobacterium tuberculosis, the causative organism of the disease tuberculosis (TB) in humans, leads to nearly two million deaths each year. This versatile pathogen can exist in highly distinct physiological states such ... -
Topoisomerase i from mycobacterium tuberculosis : Dynamics of enzyme function and inhibitor development
Inside the bacterial cell, the genetic material is maintained in a negatively supercoiled state within a compact space. The supercoiling of the genome undergoes topological perturbations during a variety of cellular processes ... -
Uncovering the Role of Mitochondrial Iron-sulfur (Fe-S) Cluster Biogenesis in Human Health and Disease
(2018-09-04)Mitochondrial dysfunction has been implicated for a wide range of human diseases. One of the major biosynthetic processes in human mitochondria is the biogenesis of Iron-Sulfur (Fe-S) clusters which primarily involves in ... -
Understanding in vivo Significance of Allosteric Regulation in mtHsp70s : Revealing its Implications in Parkinson's Disease Progression
(2018-01-28)Mitochondria are essential eukaryotic organelles, acting as the sites for numerous crucial metabolic and signalling pathways. The biogenesis of mitochondria requires efficient targeting of several hundreds of proteins from ... -
Understanding Patterns of Bird Species Distribution in the Western Ghats
(2018-06-23)Macroecology is the study of relationships between organisms and the environment at large spatial and temporal scales. This field of research examines patterns in species abundance, distribution and diversity. Understanding ... -
