Causes and Consequences of Hetrospecific Foraging Associations in Terrestrial Bird Communities
(2018-04-12)The question of group-living in animals has attracted a lot of research attention. Today, we have a nuanced understanding of ultimate explanations and proximate mechanisms for group-living, as well as the genetic basis for ... -
Conformational Analysis of Designed and Natural Peptides : Studies of Aromatic/Aromatic and Aromatic/Proline Interactions by NMR
(2018-04-05)This thesis describes NMR studies which probe weak interactions between amino acid side chains in folded peptide structures. Aromatic/aromatic interactions between facing phenylalanine residues have been probed in antiparallel ... -
Deciphering Structure-Function Relationships in a Two-Subunit-Type GMP Synthetase by Solution NMR Spectroscopy
(2018-04-24)The guanosine monophosphate synthetase (GMPS) is a class I glutamine amidotransferase, involved in the de-novo purine nucleotide biosynthesis. The enzyme catalyzes the biochemical transformation of xantosine (XMP) into ... -
DNA Double-Strand Break Repair : Molecular Characterization of Classical and Alternative Nonhomologous End Joining in Mitochondrial and Cell-free Extracts
(2018-04-05)Maintenance of genomic integrity and stability is of prime importance for the survival of an organism. Upon exposure to different damaging agents, DNA acquires various lesions such as base modifications, single-strand ... -
Elucidating the Role of MsRbpA in Rifampicin Tolerance and Transcription Regulation of Mycobacterium Smegmatis
(2018-04-12)RNA polymerase binding protein A (RbpA) was first discovered as a RNA polymerase binding protein from Streptomyces. coelicolor. It was shown to cause rifampicin tolerance to RNA polymerase in vitro and leads to basal level ... -
GABAA Receptor Mediated Phasic and Tonic Inhibition in Subicular Pyramidal Neurons
(2018-07-28)GABA is the major inhibitory neurotransmitter in the central nervous system. It binds to two types of receptors –ionotropic GABAA and metabotropic GABAB. The GABAA receptor directly gates a Clionophore that causes ... -
Genetics of Glioma : Transcriptome and MiRNome Based Approches
(2018-03-26)Glioma, the tumor of glial cells, is one of the common types of primary central nervous system (CNS) neoplasms. Astrocytoma is the most common of all gliomas and originates from astrocytic glial cells. Astrocytoma tumors ... -
Host Gene Expression Profiling of Japanese Encephalitis Virus Infected cells : Identification of Novel Pro- and Anti-viral Genes
(2017-11-27)Japanese encephalitis virus (JEV), a mosquito-borne flavivirus is the causative agent of Japanese encephalitis (JE). The disease affects mostly children and around 30000– 50000 cases of JE and up to 15000 deaths are reported ... -
How Much Initiator tRNA Does Escherichia Coli Need?
(2017-11-27)The work discussed in this thesis deals with the significance of initiator tRNA gene copy number in Escherichia coli. A summary of the relevant literature discussing the process of protein synthesis, ... -
Identification of the Minimal Domain of RNA Trihosphastase Activity in the L Protien of Rinderpest Virus and Charecterization of its Enzymatic Activities
(2018-04-03)Morbilliviruses belong to the family Paramyxoviridae of the Mononegavirale order of viruses. The Mononegavirale order contains viruses which contain negatively-polar, non-segmented and single stranded RNA genomes. This ... -
Identification of Therapeutic Targets for Oral Squamous Cell Carcinoma
(2018-04-03)Oral squamous cell carcinoma (OSCC) is the most common head and neck cancer, with a worldwide incidence of 275,000 new cases annually (Warnakulasuriya, 2009). Globally, the head and neck carcinoma represents a major cause ... -
Implications of Soluble Diacylglycerol Acyltransferases in Triacylglycerol Biosynthesis in Yeast and Plants
(2018-04-12)Lipids are stored in a cell for providing energy. The main advantages of storing lipids over carbohydrates like glycogen is that, lipids yield more energy after oxidation because they represent the highly reduced form of ... -
Infection of Human Cell Lines by Japanese Encephalitis Virus : Increased Expression and Release of HLA-E, a Non-classical HLA Molecule
(2018-04-24)Japanese encephalitis virus (JEV) causes viral encephalitis in new born and young adults that is prevalent in different parts of India and other parts of South East Asia with an estimated 6000 deaths per year. JEV is a ... -
Insights into Occurrence and Divergence of Intrinsic Terminators and Studies on Rho-Dependent Termination in Mycobacterium Tuberculosis
(2018-04-11)Two mechanisms, intrinsic and factor-dependent, have evolved for accomplishing the termination of transcription in eubacteria. In this thesis, the first chapter is an introduction to the topic that presents what is known ... -
Investigations on the Possible Role of Aromatic β-Glucoside Metabolism in Self-Defense in Enterobacteriaceae
(2018-04-02)Bacteria are ubiquitous in all ecosystems and are often challenged by multiple stresses such as extreme temperatures, high salt concentrations, nutrient limitation, pH variations, radiation, predation and the presence of ... -
