Solution NMR Studies Of Peptide Toxins From Cone Snails And Scorpion
(2010-09-13)Major constituents of the venom of various animals are peptidogenic in nature. Marine snails belonging to the species Conus are venomous predators that use small, structurally constrained peptides present in their venom ... -
Structure-Function Studies On Triosephoshate Isomerase From Plasmodium falciparum And Methanocaldococcus jannaschii
(2010-08-16)This thesis describes studies directed towards understanding structure-function relationships of triosephosphate isomerase (TIM), from a protozoan parasite Plasmodium falciparum and a thermophilic archaea Methanocaldococcus ... -
Structure-Function Correlations In Aminoacyl tRNA Synthetases Through The Dynamics Of Structure Network
(2010-08-16)Aminoacyl-tRNA synthetases (aaRSs) are at the center of the question of the origin of life and are essential proteins found in all living organisms. AARSs arose early in evolution to interpret genetic code and are believed ... -
Orienting Macromolecule At The Air - Water Interface : DNA-Protein Interaction On Langmuir Films
(2010-07-23)The Langmuir – Blodgett (LB) technique is about forming insoluble monolayer on the surface of aqueous solution and recently, it has emerged as one of the best method to study floating monolayer at the air – water interface. ... -
Epileptiform Activity Induced Alterations In Ca2+ Dynamics And Network Physiology Of Hippocampal Neurons - In Vitro Studies
(2010-07-15)Epilepsy is characterized by the hyperexcitability of individual neurons and hyper synchronization of groups of neurons (networks). The acquired changes that take place at molecular, cellular and network levels are important ... -
Unusual Acylation Properties Of Type II Fatty Acid Biosynthesis Acyl Carrier Proteins
(2010-07-06)This thesis entitled ‘ Unusual Acylation Properties of Type II Fatty Acid Biosynthesis Acyl Carrier Proteins’ describes the discovery of self-acylation and malonyl transferase activity in acyl carrier proteins involved in ... -
Solution NMR Studies Of E.Coli Acetohydroxy Acid Synthase (AHAS) I
(2010-04-13)Branched chain amino acids are classified as essential amino acids since their biosynthetic routes or pathways are restricted only to micro-organisms, fungi and plants. Given their unique distribution, the enzymes of the ... -
Genome-Wide And Structural Analyses Of Protein Kinase Superfamily
(2010-04-12)A signal transduction process refers to chain of highly regulated biochemical steps which results in the transfer of signal in response to a stimulus in the extracellular environment to the intracellular compartments such ... -
Estradiol Induced Changes In Neuronal Excitability And Neuron-Astrocyte Signaling In Mixed Hippocampal Cultures
(2010-03-02)One of the defining characteristics of the brain is its plasticity, which is the ability to alter and reorganize neuronal circuits. The brain is constantly being shaped and moulded by the external world through endogenous ... -
Structural Studies On Mycobacterium Smegmatis Dps Molecules
(2010-02-22)Oxidative stress is a universal phenomenon experienced by both aerobic and anaerobic organisms. Reactive oxygen species (ROS) are generated during the stress, which can damage most cellular components including proteins, ... -
Exploring Protein-Nucleic Acid Interactions Using Graph And Network Approaches
(2009-09-22)The flow of genetic information from genes to proteins is mediated through proteins which interact with the nucleic acids at several stages to successfully transmit the information from the nucleus to the cell cytoplasm. ... -
Structural Studies On Three Pyridoxal-5'-Phosphate Dependent Enzymes : N-Acetylornithine Aminotransferase, Serine Hydroxymethyltransferase And Diaminopropionate Ammonia Lyase
(2009-09-02)Pyridoxal 5’-phosphate (PLP), the active form of vitamin B6, is a cofactor for many enzymes involved in the metabolism of amino acids, amino acid derived metabolites and some amino sugars. PLP is one of the most versatile ... -
Computational And Biochemical Studies On The Enzymes Of Type II Fatty Acid Biosynthesis Pathway : Towards Antimalarial And Antibacterial Drug Discovery
