Design and Characterization of HIV-1 ENV Derived Immunogens
(2018-06-21)The Human Immunodeficiency Virus (HIV) is a member of the retroviridae family from lentivirus genus which primarily infects CD4+ T cells and also to lesser degree monocytes, macrophages, and dendritic cells causing progressive ... -
Development of a Selective Cell-Permeable Protein Phosphatase 1 Inhibitor
(2018-07-10)Selective ‘super-specific’ inhibitors of Protein Phosphatase 1 (PP1) are not available. Several natural product toxins possessing marginal selectivity between PP1 and the closely related Protein Serine/Threonine Phosphatase ... -
Further Structural Studies on Jacalin and Genomics Search for Mycobacterial and Archeal Lectins
(2017-12-03)This thesis consists of two parts. The first part is concerned with further structural and related studies of jacalin, one of the two lectins found in jack fruit seeds. The second part deals with the search of mycobacterial ... -
Modulation of Protein Stability and Function by Cysteine Mutations and Signal Peptides
(2018-06-23)Chapter 1gives a general introduction to the CXXC motif found in natural proteins. It then reviews the studies where disulphides were engineered in various proteins. The various strategies developed to engineer metal binding ... -
Molecular Determinants of Mutant Phenotypes in the CcdAB Toxin -Antitoxin System
(2018-05-29)A major challenge in biology is to understand and predict the effect of mutations on protein structure, stability and function. Chapter 1 provides a general introduction on protein sequence-structure relationships and use ... -
NMR Solution Structures of Human γC-Crystallin & the Intrinsically Disordered Viral Genome Linked Protein in the Free & Bound Form
(2018-02-14)This thesis describes the tertiary structures and dynamic studies of two protein systems. The first is human γC -crystallin protein, which is present in the nucleus of the human eye lens and the other is the plant viral ... -
Role of Lactate and TREK1 Channels in Neuroprotection during Cerebral Ischemia – in Vitro Study in Rat Hippocampus
(2017-12-16)Cerebral ischemia is a highly debilitating condition where shortage of oxygen and glucose leads to profuse cell death. Insufficient blood supply to the brain leads to cerebral ischemia and increase in extracellular lactate ... -
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 ... -
Sequence And Structural Determinants of Helices in Membrane Proteins
(2017-09-23)Membrane proteins roughly constitute 30% of open reading frames in a genome and form 70% of current drug targets. They are classified as integral, peripheral membrane proteins and polypeptide toxins. α-helices and β -strands ... -
Structural and Functional Studies on Salmonella typhimurium Propionate Kinase and Photorhabdus luminescens Oxalate Decarboxylase
Acetate and propionate are low molecular mass carbon compounds found abundantly in the soil. Although these compounds have been extensively used as food preservatives because of their ability to inhibit microbial growth, ... -
Structural and Mechanistic Features of Protein Assemblies with Special Reference to Spliceosome
(2017-12-07)Macromolecular assemblies such as the ribosome, spliceosome, polymerases are imperative for cellular functions. The current understanding of these important machineries and many other assemblies at the molecular level is ... -
Structural and Related Studies on Mycobacterial RecA and LexA
(2018-06-18)Genetic material of bacteria is subject to damage due to multitudinous factors, both extrinsic and intrinsic in origin. Mechanisms for the maintenance of genomic integrity are thus essential for a bacterium to survive. ... -
Structural Studies on DNA Damage Inducible Protein 1 (Ddi1) of Leishmania and the Rotavirus Nonstructural Protein NSP4
(2018-01-17)Structuraj investigations on the Ddi1 (DNA-damage inducible protein 1) of Leishmania major and on the rotavirus nonstructural protein NSP4 were carried out. Ddi1 belongs to the ubiquitin receptor family of proteins. One ... -
Structure Determination of Proteins of Unknown Origin by a Marathon MR Protocol and Investigations on Parameters Important for Molecular Replacement Structure Solution
(2018-02-20)Occasionally, crystallisation of proteins works in mysterious ways! One might obtain crystals of a protein of unknown identity in place of the protein for which crystallisation experiments were performed. If the investigator ... -
Structure- Function Studies on Triosephosphate Isomerase : Some Old Questions, Some New Insights
This thesis describes biophysical, kinetic, structural, and sequence conservation analysis of the glycolytic enzyme triosephosphate isomerase (TIM). TIM catalyses the diffusion limited isomerization of D-glyceraldehyde-3-phospahte ... -
Subthreshold Conductances Regulate Theta-Frequency Local Field Potentials and Spike Phase
(2018-02-21)Local field potentials (LFPs), extracellular potentials that reflect localized electrical activity, have long been used as a window to understand the behavioural dependence and mechanistic aspects of brain physiology. A ... -
A Systems Biology Approach towards Understanding Host Response and Pathogen Adaptation in Latent Tuberculosis Infection
(2018-01-04)Mycobacterium tuberculosis, the etiological agent of tuberculosis, has adapted with the host environment and evolved to survive in harsh conditions in the host. The pathogen has successfully evolved strategies not only to ...
