Role of Escherichia coli UvrD helicase in resolving G-quadruplex DNA structures
G-quadruplex (G4) secondary structures have been implicated in various biological processes, including gene expression, DNA replication and telomere maintenance. However, unresolved G4 structures impede replication ... -
Role of Mycobacterium tuberculosis UvrD1 and UvrD2 helicases in resolving G-quadruplex DNA structures
Unresolved G-quadruplex (G4) DNA secondary structures impede DNA replication and can lead to DNA breaks and to genome instability. Helicases are known to unwind G4 structures and thereby facilitate genome duplication. ... -
Role of PdtaS-PdtaR two component signalling system in metabolic adaptation in Mycobacterium spp.
The ability to perceive and adapt to environmental fluctuations, both internal and external, is a fundamental characteristic of life across diverse organisms. Within the context of pathogenic bacteria such as Mycobacterium ... -
Role of Sirtuin 2 in the development of tissue fibrosis
Wound healing is a crucial physiological process required for the healthy lifespan of an organism. Dysregulation in the process of wound healing leads to the production of excess extracellular matrix leading to fibrosis. ... -
Rv0805, a novel regulator of central carbon metabolism and cell envelope properties in mycobacteria
Metabolic flexibility is one of the key factors that underpin mycobacterial physiology and pathogenesis. During infection, mycobacteria shift towards utilising host-derived fatty acids, lipids, cholesterol and cholesterol-esters. ... -
Solution NMR studies of a potent subtilisin inhibitor from Budgett’s frog and the catalytic subunit of AHAS
This thesis involves a detailed structural study of two molecular systems, a small disulfide-rich peptide LL-TIL and a large catalytic subunit of AHAS. Subtilisin inhibitors play an important role in fighting against ... -
Structural and functional insights into hybrid AT-less megaenzyme synthase (NRPS) and DNA-MsDps2 complexes using single particle cryo-EM
Microorganisms, mainly bacteria and fungi, are the producers of structurally diverse, complex organic compounds called as secondary metabolites. These metabolites include polyketides (PKs), non-ribosomal peptides (NRPs), ... -
Structural, mechanistic and pharmacological studies of inhibitory neurotransmitter transporters
Gamma-aminobutyric acid (GABA) is the major inhibitory neurotransmitter in the central nervous system (CNS). The synaptic levels of GABA are controlled by the activity of GABA transporters (GATs) present in the presynaptic ... -
Structure analysis of lectin and lectin-like domains from Entamoeba histolytica
Lectins are a diverse group of proteins which can recognize different types of carbohydrates specifically and reversibly. Though first characterized in plants, lectins have now been identified in all other forms of life. ... -
Transcriptional Regulation of Fatty Acid Transport by Sirtuin 2
The heart is a highly dynamic organ and under normal physiological conditions, it is heavily dependent on fatty acid oxidation to meet its energy requirements (Abumrad and Goldberg 2016). Fatty acid transport is a crucial ... -
Understanding protein structural excursions using residue networks and implications on biological function
The information required for a protein structure to fold into the native conformation is encoded in its sequence. Studying protein structures help to understand their biological function. Molecular interactions between ... -
Understanding structure, function, and dynamics in macromolecular complexes
In the scope of my thesis work, a concerted effort was undertaken to elucidate bi- ological functions through the lens of structural analysis, employing protein dy- namics. The role of protein dynamics in shaping and ... -
Understanding the interaction mechanism of bacterial virulence factors and effector proteins with host lipid membrane using single particle cryo-electron microscopy
Pathogenic bacteria employ an array of biological macromolecules and cellular structures that help in the initiation and progression of disease in host organism. These ‘virulence factors’ can either be secreted by the ... -
Understanding the redox homeostatic mechanisms in Mycobacterium tuberculosis infection
Mycobacterium tuberculosis (Mtb) is an obligate intra-cellular pathogen that causes the disease tuberculosis (TB) in its human hosts. An estimated 1% of the world population is reported to get infected with the disease ...
