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 ... -
Expanding The Horizon Of Mycobacterial Stress Response : Discovery Of A Second (P)PPGPP Synthetase In Mycobacterium Smegmatis
(2015-12-21)The stringent response is a highly conserved physiological response mounted by bacteria under stress (Ojha and Chatterji, 2001; Magnusson et al., 2005; Srivatsan and Wang, 2007; Potrykus and Cashel, 2008). Until recently, ... -
Exploring The Role Of The Highly Conserved Residues In Triosephosphate Isomerase
(2014-08-11)This thesis discusses the structure-function studies on triosephosphate isomerase (TIM) from Plasmodium falciparum (Pf), directed towards understanding the roles of highly conserved residues by site derected mutagenesis. ... -
Functionally Interacting Proteins : Analyses And Prediction
(2016-05-04)Functional interaction of proteins is a broad term encompassing many different types of associations that are observed amongst proteins. It includes direct non-covalent interactions where the interacting proteins physically ... -
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 ... -
Intracellular Calcium Dynamics In Dendrites Of Hippocampal Neurons Rendered Epileptic And In Processes Of Astrocytes Following Glutamate Pretreatment
