Structural and Related Studies on Mycobacterial Lectins
(2018-05-09)This thesis is concerned with the first ever X-ray crystallographic and complimentary solution studies on mycobacterial lectins. Lectins, described as multivalent carbohydrate binding proteins of non-immune origin, are ... -
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 and related studies on Mycobacterium tuberculosis pantothenate kinase
Pantothenate kinase (PanK) is a ubiquitous and essential enzyme that catalyses the first step in the universal Coenzyme A (CoA) biosynthetic pathway. In this step pantothenate is converted to phosphopantothentate, which ... -
Structural Characterization of Biological Macromolecules by Random Conical Tilt Pair Experiments
Structural biology deals with determining the structure of biological macromolecules especially proteins, DNA, RNA. The conformational changes in the structure of a macromolecule helps to decipher its function. This ... -
Structural Characterization Of Protein Folding Intermediates

Structural characterization of Staphylococcal γ-hemolysin in the presence of a lipid environment using single particle cryo-EM
γ-Hemolysin (γ-HL) is a quintessential bicomponent β-pore forming toxin (β-PFT) belonging to the arsenal of “superbug” Staphylococcus aureus. Here, we performed negative staining-TEM and single particle cryo-EM-based ... -
Structural Feature of Prokaryotic Promoters and their Role in Gene Expression
(2018-05-14)Transcription initiation is an important step in the process of gene regulation in prokaryotes. Promoters are stretches of DNA sequence that are present in the upstream region of transcription start sites (TSSs), where RNA ... -
Structural insights into assembly and regulation of HigBA toxin-antitoxin system from Escherichia coli
In the last few decades, bacterial Toxin-antitoxin (TA) systems have been identified to play crucial roles in bacterial survival under stressful conditions and virulence. TA systems are pair of genetic elements where one ... -
Structural insights into the organization and channel behavior of Pannexin isoforms
Pannexins are large-pore ion channels structurally related to Connexins and Innexins but remain as hemichannels to release cellular ATP upon activation. Pannexins comprise three isoforms, Pannexin1, 2, and 3, with diverse ... -
Structural Insights of Inter-domain Interactions in Multi-domain Proteins
Embargo up to August 11, 2026. Proteins are essential biomolecules whose diverse functions stem from their modular architecture built from independently folding units called domains. This thesis investigates the nature and ... -
Structural Investigations Of Sugar-Binding And Multivalency In Peanut Lectin
(2009-03-04)Starting with the structure analysis of ConA in the 70s, the crystal structures of hundreds of different lectins and their carbohydrate complexes have been determined. Lectins, multivalent carbohydrate-binding proteins ... -
Structural investigations on mycobacterial RecA
RecA protein plays a crucial role in homologous genetic recombination, DNA repair, and SOS induction. Homologous recombination involves genetic exchange between any two DNA molecules sharing extended regions with homologous ... -
Structural kinetic and mechanistic aspects of the carboxylic ionophore mediated transmembrane cation transport
Maintenance of ionic gradients across biological membranes has been established to be achieved mainly by an interplay of two mechanisms, namely, the carrier mechanism and the channel mechanism. In the carrier mechanism, ... -
Structural Studies Of E. Coli Thioredoxin And P. Falciparum Triosephosphate Isomerase By NMR And Computational Methods
(2014-05-21)To unravel the mysteries of complex biological processes carried out by biomolecules it is necessary to adopt a multifaceted approach, which involves employing a wide variety of tools both computational and experimental. ... -
Structural Studies Of Mycobacterial Uracil-DNA Glycosylase (Ung) And Single-Stranded DNA Binding Protein (SSB)
(2011-09-21)For survival and successful propagation, every organism has to maintain the genomic integrity of the cell. The information content, in the form of nucleotide bases, is constantly threatened by endogenous agents and ... -
Structural Studies on Bacterial Adenylosuccinate Lyase and Sesbania Mosaic Virus Protease
(2018-05-08)The three-dimensional structures of biological macromolecules and molecular assemblies are becoming increasingly important with the changing methodologies of drug discovery. The structures aid in understanding of protein ... -
Structural Studies On Basic Winged Bean Agglutinin
(2009-07-03)The journey of structural studies on lectins, starting with ConA in the 70s, has crossed many milestones. Lectins, multivalent carbohydrate-binding proteins of non-immune origin, specifically bind diverse sugar structures. ... -
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 ...
