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 ... -
Crystallographic and analytical ultracentrifugation studies of the E. coli acetohydroxy acid synthase I enzyme
This thesis ellucidates the mechanism of activation and regulation of AHAS I enzyme from Escherichia coli that was characterised using crystallographic and sedimentation velocity analytical ultracentrifugation studies. AHAS ... -
Cyclic peptide disulfides as conformational models; synthesis and spectroscopic studies
The study of small peptides has been motivated both by the high biological activity manifested by many peptides and their potential use as model systems for understanding polypeptide and protein structure. The development ... -
Deciphering Structure-Function Relationships in a Two-Subunit-Type GMP Synthetase by Solution NMR Spectroscopy
(2018-04-24)The guanosine monophosphate synthetase (GMPS) is a class I glutamine amidotransferase, involved in the de-novo purine nucleotide biosynthesis. The enzyme catalyzes the biochemical transformation of xantosine (XMP) into ... -
Decoding determinants of selectivity in biomolecules
Molecular events demonstrate remarkable specificity amid complexity in its cellular environment. This phenomenon, termed biomolecular recognition, is fundamental to the organization and regulation of biological systems. ... -
Deep Mutational Scanning Analyses of Protein Stability and Function
Full text Embargo up to Sep 2026 Protein stability is critical to understanding protein function, folding, and interactions within living organisms. It plays a key role in protein engineering, where designing stable ... -
Deep mutational scanning to enhance immunogenicity and map antibody responses to HIV-1
Vaccines have proven effective against numerous viral diseases, yet the development of a successful vaccine for Human Immunodeficiency Virus (HIV-1) remains elusive. A key immunogen for vaccine design is the surface ... -
Design and Characterization of HIV-1 ENV Derived Immunogens
(2018-06-21)The Human Immunodeficiency Virus (HIV) is a member of the retroviridae family from lentivirus genus which primarily infects CD4+ T cells and also to lesser degree monocytes, macrophages, and dendritic cells causing progressive ... -
Design and characterization of stabilized mutants of the SARS-CoV-2 Receptor Binding Domain
The global pandemic caused by SARS-CoV-2 has resulted in millions of deaths worldwide, highlighting the urgent need for effective vaccines. The trimeric spike glycoprotein, particularly the receptor-binding domain (RBD), ... -
Design And Isolation Of Temperature Sensitive Mutants Of Gal4 In Yeast And Drosophila
(2009-04-16)Genomic and proteomic investigations have yielded, and continue to produce, a large amount of information about genes and their protein products. In contrast, the evidence bearing on physiological roles of specific proteins ... -
Design and Stabilization of Stem Derived Immunogens from HA of Influenza A Viruses
(2018-07-19)Influenza virus belongs to the Orthomyxovirus family of viruses that causes respiratory infection in humans, leading to morbidity and mortality. The mature influenza A virion has an envelope that contains two major surface ... -
Design of a thermostable pan-sarbecovirus vaccine
Coronaviruses (CoVs) are a global health threat due to their potential for widespread transmission including in humans. Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), the etiological agent responsible for ... -
Design of Immunogens Derived from the Conserved Stem of Influenza Virus Hemagglutinin
Influenza viruses can cause respiratory illnesses and are very contagious, leading to either pandemics or seasonal epidemics and resulting in significant mortality and morbidity rates. The main symptoms of the influenza ... -
Design of Influenza Immunogens by Hemagglutinin (HA) Protein Minimization
(2018-01-31)Influenza virus is a pleiomorphic human pathogen which causes self-limiting respiratory illness lasting one-two weeks in most individuals. However, in immunologically compromised individuals, influenza infection may lead ... -
Design of soluble and particulate immunogens derived from the stem of Influenza hemagglutinin
Influenza is a highly contagious virus, belonging to the family Orthomyxoviridae that causes acute febrile respiratory illness which can be fatal in some cases. The highest risk groups for influenza viral infection ... -
