Design and Stabilization of Stem Derived Immunogens from HA of Influenza A Viruses
(2018-07-19)
Influenza virus belongs to the Orthomyxovirus family of viruses that causes respiratory infection in humans, leading to morbidity and mortality. The mature influenza A virion has an envelope that contains two major surface ...
Structural and Functional Studies on Pyridoxal Kinase and Pyridoxal 5′-phosphate Dependent Enzymes
(2018-07-04)
Most of the chemical reactions of living cells are catalyzed by protein enzymes. These enzymes are very efficient and display a high degree of specificity with respect to the reaction catalyzed. Cellular activities depend ...
Estradiol Induced Changes In Neuronal Excitability And Neuron-Astrocyte Signaling In Mixed Hippocampal Cultures
(2010-03-02)
One of the defining characteristics of the brain is its plasticity, which is the ability to alter and reorganize neuronal circuits. The brain is constantly being shaped and moulded by the external world through endogenous ...
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 ...
Solution NMR Studies Of Peptide Toxins From Cone Snails And Scorpion
(2010-09-13)
Major constituents of the venom of various animals are peptidogenic in nature. Marine snails belonging to the species Conus are venomous predators that use small, structurally constrained peptides present in their venom ...
Structure-Function Correlations In Aminoacyl tRNA Synthetases Through The Dynamics Of Structure Network
(2010-08-16)
Aminoacyl-tRNA synthetases (aaRSs) are at the center of the question of the origin of life and are essential proteins found in all living organisms. AARSs arose early in evolution to interpret genetic code and are believed ...
Structure-Function Studies On Triosephoshate Isomerase From Plasmodium falciparum And Methanocaldococcus jannaschii
(2010-08-16)
This thesis describes studies directed towards understanding structure-function relationships of triosephosphate isomerase (TIM), from a protozoan parasite Plasmodium falciparum and a thermophilic archaea Methanocaldococcus ...
