Intracellular Calcium Dynamics In Dendrites Of Hippocampal Neurons Rendered Epileptic And In Processes Of Astrocytes Following Glutamate Pretreatment
(2009-04-03)
The fundamental attribute of neurons is their cellular electrical excitability, which is based on the expression of a plethora of ligand- and voltage-gated membrane channels that give rise to prominent membrane currents ...
Thermodynamic Characterization Of Wild Type And Mutants Of The E.coli Periplasmic Binding Proteins LBP, LIVBP, MBP And RBP
(2009-03-13)
Native states of globular proteins typically show stabilization in the range of 5 to
15 kcal/mol with respect to their unfolded states. There has been a considerable progress in the area of protein stability and folding ...
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 ...
Mechanism Of Interaction Of Escherichia Coli σ70 With Anti-Sigma Factors
(2009-08-03)
In bacteria, the RNA polymerase (RNAP) consists of the following subunits: α2, β, β’, ω and σ. The core RNAP (α2ββ’ω) possesses the polymerising activity and it associates with one of the sigma factors to initiate transcription ...
Structural Studies On The Enzymes FabI And FabZ Of Plasmodium Falciparum
(2008-10-20)
The thesis deals with X-ray crystallographic analysis of two enzymes involved in the fatty
acid biosynthesis pathway, known as Fatty Acid Synthase or FAS, of the malarial parasite, Plasmodium falciparum, in order to ...
Design And Isolation Of Temperature Sensitive Mutants Of Gal4 In Yeast And Drosophila
(2009-04-16)
Genomic and proteomic investigations have yielded, and continue to produce, a large amount of information about genes and their protein products. In contrast, the evidence bearing on physiological roles of specific proteins ...
Understanding the Regulatory Steps that Govern the Activation of Mycobacterium Tuberculosis σK
(2018-07-28)
A distinctive feature of host-pathogen interactions in the case of Mycobacterium tuberculosis is the asymptomatic latent phase of infection. The ability of the bacillus to survive for extended periods of time in the host ...
Structural and Evolutionary Analyses of Signalling Proteins with Special Reference to Protein Kinases
(2018-02-27)
Cellular response to environmental changes involves a wide repertoire of complex signalling systems often resulting in up and down regulation of various genes. These mechanisms are generally conserved in a variety of ...
Solution Structure Studies on the Effects of Aromatic Interactions and Cross-Strand Disulfide Bonds on Protein Folding
(2018-07-05)
The work presented in this thesis focusses primarily on the determination of protein structure at atomic resolution, with NMR spectroscopy as the principle investigative tool. The thesis is divided into four parts. Part I ...
Secondary Structures in Proteins : Identification and Analyses
(2018-07-12)
Proteins are large biomolecules consisting of one or more long chains of amino acid residues. They perform a vast array of functions within living organisms. In this thesis, we present analyses of different secondary ...
