Biochemical, Biophysical and Evolutionary Perspectives of Zinc Finger Proteins in Mycobacterium smegmatis
(2018-05-21)Transcription is a major step in expression of genes of a given organism. Due to environmental constrains this step must be regulated in the favour of the sustenance and growth of the organism. Here comes the relevance of ... -
Biophysical Studies on Mycobacterium Tuberculosis σ Factor – Regulatory Protein Complexes
Adaptation to external environmental conditions is essential for the survival of a bacterial cell. Bacteria have thus evolved multiple mechanisms to sense environmental stimuli and to couple this information into an ... -
Crystallization and Preliminary Structural Studies on Mycobacterium tuberculosis RuvX
The deadly pathogen Mycobacterium tuberculosis has been characterized for its virulence in immense detail. Regardless of this, the capability of M. tuberculosis to combat extreme stress conditions inside the host cell for ... -
Dynamics of Protein Kinases : Its Relationship to Functional Sites and States
(2018-05-22)A cell is a highly complex, ordered, and above all, a robust system. It copes with in-trennel and external uncertainties like heterogeneous stimuli, errors in processing and execution, and changes within and outside the ... -
Effect of Ultrasound on Neuronal Network Communication
(2018-05-22)Low intensity and low frequency ultrasound has been shown to modulate ion channel currents, membrane capacitive currents, and as a result, neuronal activity. Ultrasound has been used as a non-invasive way to modulate ... -
Effects of Cyclic Permutation, Glycan Removal and Aspartate Mutagenesis on Conformation of HIV-1 Envelope
It has been decades since Human Immunodeficiency Virus-1 (HIV-1) was discovered. The virus has created havoc worldwide. According to the UNAIDS 2014 Gap report, 35million people worldwide are infected with HIV-1 and yet ... -
G-Protein Coupled Estrogen Receptor (hGPER)- Mediated Action of 17β-Estradiol on hTREK-1 Potassium Channel
TREK-1 is a two-pore domain potassium channel that contributes to maintenance of the resting membrane potential of a cell. TREK-1 is involved in several physiological and pathophysiological conditions like nociception, ... -
Pranlukast as an Allosteric Inhibitor of M.Tuberculosis Ornithine Acetyltransferase : Implication Towards Novel Combinatorial Therapy
Tuberculosis (TB) is a deadly disease responsible for the death of approximately 1.5 million people each year, with the highest being from developing nations. Tuberculosis affects mostly the lungs, and other parts of the ... -
Protein Structure and Mutant Phenotype Prediction from Analysis of Mutant Libraries by Deep Sequencing
Proteins play a central role in all the biological processes. The immense diversity in protein structures and functions despite similar underlying composition is intriguing. The work presented in this thesis aims to provide ... -
Role of RNA Polymerase ω Subunit in Metabolism and Stress Response
RNA polymerase (RNAP) is the key enzyme in transcription and it is a multi-subunit enzyme made up of alpha, beta, beta prime and omega subunit in the stoichiometry of α2ββω. Except for the smallest subunit ω (rpoZ), all ... -
Role of Second (p)ppGpp Synthetase MS_RHII-RSD in Mycobacterium smegmatis
Adaptation to a rapidly fluctuating environment is the key to the survival of an organism. Bacteria sense and respond to stress by an overall reprogramming of the cellular processes to shut down the energy-consuming processes ... -
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 ... -
Structural and Biochemical Studies on Mycobacterial Uracil- DNA N-glycosylase and Mut T1
Maintenance of the genomic integrity of the cell is crucial for the survival and successful propagation of an organism. However, this integrity is under continuous threat from DNA-damaging agents. In addition, errors in ... -
Structural and Functional Characterisation of Small Heat Shock Protiens from Mycobacterium Marinum M
Small Heat Shock Proteins (sHSP) are ATP-independent molecular chaperones that exhibit diversity in structure, function and mode of action. They are present ubiquitously in all kingdoms of life. They function mainly by ... -
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 ... -
Structural and Functional Studies on the Mycobacterium tuberculosis σ factor σJ
(2018-05-21)Regulation of transcription in prokaryotes is primarily governed at the transcription initiation step. This feature has been extensively characterized in model prokaryotes notably Escherichia coli and Bacillus subtilis. ... -
Structural Studies on Non-toxic Homologues of type II Ribosome Inactivating Proteins (RIPs)
This thesis is concerned with structural and related studies on two non-toxic homologues of type II RIPs. Type II RIPs, which are more toxic than type I, contain an additional lectin chain (B-chain) covalently linked to ... -
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 ... -
Synergistic Influence of Gene Architecture and Promoter Structure on Transcription in Plants : An in silico Analysis
Understanding the structural organisation of genome and insightful information of gene has helped in exploring the regulation and expression of the gene at a molecular and cellular level. In eukaryotes, the gene regulation ...
