Structure Analysis Of Plant Lectin Domains
(2014-04-07)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 ... -
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 Relationship In Tryptophanyl tRNA Synthetase Through MD Simulations & Quantum Chemical Studies On Unusual Bonds In Biomolecules
(2010-10-21)Biological processes are so complicated that to understand the mechanisms underlying the functioning of biomolecules it is inevitable to study them from various perspectives and with a wide range of tools. Understanding ... -
Structure Function Studies Of Biologically Important Simple Repetitive DNA Sequences
(Indian Institute of Science, 2007-03-09)The recent explosion of DNA sequence information has provided compelling evidence for the following facts. (1) Simple repetitive sequences-microsatellites and minisatellites occur commonly in the human genome and (2) these ... -
Structure, Stability and Evolution of Multi-Domain Proteins
(2018-04-11)Analyses of protein sequences from diverse genomes have revealed the ubiquitous nature of multi-domain proteins. They form up to 70% of proteomes of most eukaryotic organisms. Yet, our understanding of protein structure, ... -
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 ... -
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 ... -
Studies on Efrapeptins

Studies on NMPylase and Valine Catabolism Enzymes from Mycobacterium
Post-translational modifications constitute an important arm of the regulatory mechanism in mammalian cells. Therefore, bacterial pathogens, which thrive by mimicking the host cell signaling, are proving to be difficult ... -
Studies On Sesbania Mosaic Virus Asssembly And Structure And Function Of A Survival Protein (SurE) From Salmonella Typhimurium
(2011-03-29)X-ray crystallography is a powerful method for determining the three-dimensional structures of biological macromolecules at atomic resolution. Crystallography can reliably provide the answer to many structure related ... -
Studies on the promoter specificity determinants and modulators of the prokaryotic transcription machinery
Bacteria adapt to a wide range of environmental conditions by synchronizing transcription with changes in the extracellular environment. This is achieved by the synchronized action of two-component systems, Extra Cytoplasmic ... -
Substrate Specificity Determinants of Class III Nucleotide Cyclases
(2018-07-31)Cyclic AMP and cyclic GMP (cAMP and cGMP) are important second messengers in key signal-transduction pathways that mediate various physiological functions in bacteria and eukaryotes. Adenylyl Cyclases (ACs) and Guanylyl ... -
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 ...
