Computational mechanisms underlying eye-head coordination
Gaze or eye-head coordination is an ethologically and physiologically important process that directs the visual system to objects of interest. Due to its relative simplicity, it is an ideal system to study multi-effector ... -
Computational Mechanisms Underlying the Voluntary Control of Reach Movement Planning and Execution
In everyday life we make a variety of reaching movements. Most of these reaching movements have a clear objective of bringing the hand to the spatial location of the object of interest. Although we typically do not explicitly ... -
Computational studies on interacting proteins with special reference to toxin-antitoxin systems
Proteins interact with other proteins to maintain functional homeostasis of the cell by tightly regulating cellular processes. Hence, it becomes important to understand not only the downstream effects of protein-protein ... -
Computer Modeling and Molecular Dynamics Simulation Of Angiogenins And Its Ligand Bound Complexes
(Indian Institute of Science, 2006-05-04)Computational structural biology Even with rapid advances in structure determination methods, there is a long gap to be bridged between the number of proteins that have been sequenced and the number whose three-dimensional ... -
Computer Modelling Studies On DNA Triple Helices
(2013-07-22) -
Condition-dependent signalling and mating behaviour in the tree cricket, Oecanthus henryi
Male reproductive success in systems exhibiting sexually selected traits can be driven by male mating effort in sexual signals and in the production of nuptial gifts. Male mating effort can be determined by various biotic ... -
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 ... -
Conformational Analysis Of Designed Alpha-Omega Hybrid Peptides
(2011-10-21)The insertion of ω- amino acid residues as guests into host α-peptide sequences permits expansion of the range of polypeptide secondary structures. The term ω- amino acid is used to refer to the entire family of residues ... -
Conformational Analysis of Designed and Natural Peptides : Studies of Aromatic/Aromatic and Aromatic/Proline Interactions by NMR
(2018-04-05)This thesis describes NMR studies which probe weak interactions between amino acid side chains in folded peptide structures. Aromatic/aromatic interactions between facing phenylalanine residues have been probed in antiparallel ... -
Conformational Heterogeneity, Solution Structure and Autoregulatory Roles of the MazE9 Antitoxin from Mycobacterium tuberculosis
The work presented in this thesis endeavors to decode the details of the dynamics of MazE9 antitoxin of the Mycobacterium tuberculosis MazEF9 toxin-antitoxin system and the transcriptional autoregulation effected by it. ... -
Conservation and divergence of the nucleotide excision repair pathway: Comparison of UvrB and UvrC proteins from Mycobacterium tuberculosis and Escherichia coli reveal significant differences in their functional properties
This thesis is presented in three chapters divided by topics. Chapter I will begin with an overview of literature regarding different types of DNA damage, DNA repair pathways in bacteria, properties of E. coli UvrABC ... -
Context Dependent Effects of the Transforming Growth Factor-beta Signaling and Role Played by WNT4 in the Activation of Fibroblasts
(2018-07-26)Transforming growth factor-β (TGF-β) superfamily of cytokines comprises of several members, which can broadly be sub-divided into three classes [TGF-βs, Activin/Nodal, and Bone morphogenetic proteins (BMPs)]. Most members ... -
Crystal Structure Of Jacalin At 3.0A Resolution

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 AMP In Mycobacteria Adenylyl Cyclases And Cyclic AMP Receptor Proteins
(2013-01-28)The discovery of cyclic AMP (cAMP), nearly 50 years ago by Sutherland radically altered the appreciation of metabolic regulation. Since then the presence of cAMP and its tremendous physiological impact has been demonstrated ... -
Cyclic AMP-Regulated Protein Lysine Acetylation In Mycobacteria
(2015-07-17)Tuberculosis continues to be one of the major causes of morbidity and mortality worldwide. Several mycobacterial species such as M. tuberculosis and M. africanum are responsible for causing this disease in humans. Reports ... -
Cytosolic Lysophosphatidic Acid Acyltransferase : Implications in Lipid Biosynthesis in Yeast, Plants and Human
(2018-02-11)Cytosolic LPA acyltransferase in yeast An isooctane tolerant strain of S. cerevisiae KK-12 was reported to have increased saturated fatty acid content (Miura et. al., 2000). Amongst the various genes upregulated on isooctane ...
