conformational studies on hydrogen bonded cyclic hexapeptides
In the first place, the uniqueness of any MEC within a certain region demonstrates the successful incorporation of the hydrogen?bond energy function in a minimization program. In particular, its interpolation with the ... -
Conformational studies on peptides containing alpha aminoisobutyric acid and polypeptides with alternating LD-Sequences
The results of semiempirical energy calculations on poly(Aib), varying ACO and ?(NC?C) separately and simultaneously, suggest a novel fourfold helical structure as an energetically favourable model for poly(Aib). This novel ... -
Conformational studies on polynuc leotides and nucleic acids
After an introduction to the nucleic acids and the conformational studies on them at the monomeric and polymeric levels, the need for investigations on the conformations of 3?-nucleotides is outlined. The significance of ... -
Conformationalflexibility of DNA: Polymorphism and handness
Observation of both right- and left-helical DNA fragments in the single crystals and different poly morphous forms of DNA in fibres suggest that the con formational flexibility is inherent in the DNA mole cule. However, ... -
Crystal Structure Of Jacalin At 3.0A Resolution

Crystal structure of low humidity monoclinic lysozyme at 1.75 Resolution
It has been demonstrated earlier in this laboratory that many protein crystals, but not all, undergo reversible structural transformations, as evidenced by abrupt changes in unit cell dimensions, diffraction pattern, and ... -
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 ... -
Crystallographic and modelling studies on a mannose-specific lectin from garlic bulbs
Lectins are multivalent carbohydrate-binding proteins which exert their biological effects through their ability to specifically bind different sugars. They occur in plants, animals, bacteria, and viruses. They exhibit ... -
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 ...
