Structural And Functional Studies On Staphylococcus Aureus Enzymes Involved In L-Lysine Biosynthesis
(2011-05-24)Proteins associated with metabolic pathways have received considerable attention in an effort to understand the molecular details of the complex reactions catalyzed in vivo. Enzymes belonging to these pathways have also ... -
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 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 Mechanistic Studies On Receptor Protein Tyrosine Phosphatases From Drosophila Melanogaster
(2013-06-20)Protein Tyrosine Phosphatases (PTPs) initiate, modulate and terminate key cellular processes by dephosphorylating phosphotyrosine (pY) residues on signaling proteins. The coordinated action of PTPs with their cognate ... -
Structural and mechanistic studies on Staphylococcal RNA degrading enzymes and multienzyme complexes
RNA degrading enzymes and multi-enzyme complexes govern a variety of cellular processes. The role of these enzymes and multi-enzyme assemblies has been suggested to govern gene expression levels in bacteria with modulations ... -
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 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 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 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 ... -
