Endotoxin Peptide/Protein Interactions: Thermodynamic And Kinetic Analysis
(Indian Institute of Science, 2006-05-15)Endotoxin or Lipopolysaccharide (LPS) is the invariant structural component of gram negative bacterial outer membranes and is the chief causative factor of Sepsis or endotoxic shock. Sepsis is a syndrome that has very high ... -
Energetics Of Protein-Carbohydrate Recognition
(Indian Institute of Science, 2006-04-28)The work embodied in this thesis pertains to an attempt to understand better, the molecular basis of protein-carbohydrate recognition. For this purpose a systematic study was undertaken, not only of the energetics of ... -
Evaluation Of The Efficacy Of DNA Vaccines For Japanese Encephalitis In A Murine Intracerebral Japanese Encephalitis Virus Challenge Model
(Indian Institute of Science, 2005-12-05)Japanese encephalitis virus (JEV), a member of the family flaviviridae, is one of the most important pathogens of the developing countries, causing high mortality and morbidity amongst children. The present study is aimed ... -
Functional Differentiation Of The Human Placenta : Insights From The Expression Of Two Developmentally - Regulated Genes
(Indian Institute of Science, 2005-12-08)Placenta is a transient association of the fetal and maternal tissues, that develops during pregnancy, in most viviparous animals. The evolution of placenta ensured the development of the fetus inside the womb of the mother, ... -
Garlic (Allium Sativum) Agglutinin I: Specificity, Binding And Folding Mechanism
(Indian Institute of Science, 2006-11-08)Lectins are a class of proteins that bind to carbohydrates with a high degree of specificity. They are involved in various cellular processes such as, host - pathogen interactions, targeting of proteins within cells, cell ... -
Interaction Of Chaperone SecB With Protein Substrates: A Biophysical Study
(Indian Institute of Science, 2006-10-17)In the cell, as in in vitro, the final conformation of a protein is determined by it's amino acid sequence (1). Some isolated proteins can be denatured and refolded in vitro in absence of extrinsic factors. However, in ... -
Light-And Cytokinin-Regulated Plastid And Nuclear Gene Expression In Cucumber (Cucumis Sativus L)
(Indian Institute of Science, 2005-12-06)Light and phytohormones, such as cytokinins, have been known to play a pivotal role in numerous physiological processes in plant cells. Previous work in our laboratory has revealed the light- and cytokinin- modulated changes ... -
Non-repetitive Structures In Proteins : Effects Of Side-chain And Solvent Interactions With The Backbone
(Indian Institute of Science, 2006-05-12)The work presented in this thesis deals with the analysis of protein crystal structures with an emphasis on the stereochemical aspects of the folded conformation of proteins. The various analyses described have been performed ... -
Nuclear Behaviour In Heterokaryons : Genetic And Molecular Analysis Of (his-3+ his-3+) Heterokaryons Of Neurospora Crassa
(Indian Institute of Science, 2005-12-06)In contrast to plant and animal cells, the fungal cells are multinucleate. A consequence of their multinucleate condition is heterokaryosis — the occurrence of genetically different nuclei in a common cytoplasm. In nature ... -
Structural Studies On Winged Bean Agglutinins
(Indian Institute of Science, 2007-01-11)Lectins are multivalent carbohydrate binding proteins that specifically recognise diverse sugar structures and mediate a variety of biological processes, such as cell-cell and host-pathogen interactions, serum glycoprotein ... -
