Conformational Analysis And Design Of Disulfides In Antiparallel β-Sheets And Helices
(2013-08-30)
Disulfides are the primary covalent interactions within a protein molecule that connect residues which are sequentially distant. Naturally occurring disulfides enhance the stability of the protein by destabilization of ...
Biochemical Characterization Of Heat Shock Protein 90 From Plasmodium Falciparum
(2013-06-07)
Molecular chaperones are a group of proteins which maintain cellular homeostasis by assisting de novo protein folding and their refolding to native state after destabilization due to external stress. They are also known ...
Cell Survival Strategies : Role Of Gyrase Modulatory Proteins
(2010-07-21)
A steady state level of negative supercoiling is essential for chromosome condensation, initiation of replication and subsequent elongation step. DNA gyrase, found in every eubacteria, serves the essential housekeeping ...
Metabolic Adaptation For Utilization Of Short-Chain Fatty Acids In Salmonella Typhimurium : Structural And Functional Studies On 2-methylcitrate Synthase, Acetate And Propionate Kinases
(2013-08-22)
Three-dimensional structures of proteins provide insights into the mechanisms of macromolecular assembly, enzyme catalysis and mode of activation, substrate-specificity, ligand-binding properties, stability and dynamical ...
Molecular Characterization c-di-GMP Signalling In Mycobacterium Smegmatis
(2014-07-17)
Bacterial stationary phase is an interesting biological system to study, as the organism undergoes several metabolic changes during this period and new molecules are generated to support its survival. The stationary phase ...
Structure Analysis Of FabI And FabZ Enzymes Of The Fatty Acid Biosynthesis Pathway Of Plasmodium Falciparum
(2013-08-30)
The emergence of drug resistant strains of Plasmodium has given a new face to the old disease, malaria. One of the approaches is to block metabolic pathways of the pathogen. The current thesis describes the X-ray ...
Computational And Experimental Studies On Protein Structure, Stability And Dynamics
(2014-08-18)
The work in this thesis focuses on the study of three main aspects of proteins, viz, Protein structure, stability, and dynamics. Chapter 1 is a general introduction to the topics studied in this thesis. Chapter 2 deals ...
Exploring The Role Of The Highly Conserved Residues In Triosephosphate Isomerase
(2014-08-11)
This thesis discusses the structure-function studies on triosephosphate isomerase (TIM) from Plasmodium falciparum (Pf), directed towards understanding the roles of highly conserved residues by site derected mutagenesis. ...
Designed Synthetic Peptides : Models For Studies Of Conformational Transitions And Aromatic Interactions
(2015-07-17)
This thesis set out to explore the conformational properties of short designed peptide sequences, in which transitions between structural states may be anticipated. The use of conformationally constrained residues like ...
