DNA Gyrase And Topo NM From Mycobacteria : Insights into Mechanism And Drug Action
(2017-10-26)Maintenance of a topological homeostasis by introduction and removal of the supercoils to relieve excessive strain on the DNA is a hallmark of topoisomerase function in the cell. The requirement of the topoisomerases during ... -
Dual Sites For Heme Biosynthesis In The Malarial Parasite

The Dynamics of Iron in Miniferritins : A Structure-Function Connection
(2017-11-23)The DNA binding proteins under starvation (Dps) from M. smegmatis are cage-like structures which internalize iron and bind DNA. They provide resistance to the cells from free radical damage, and physically protect the DNA ... -
Effect Of Glycodelin A On Cells Of The Immune System Insights Into GdA-Induced Signaling In Monocytes, B And NK Cells
(2010-04-06)Glycodelin is a 162 amino acid dimeric, glycosylated, secretory protein of the lipocalin superfamily. Its classification as a lipocalin(carriers of small hydrophobic molecules) is based mainly on the presence of lipocalin ... -
Elucidating the Roles of Lon Protease and its Substrate, MarA, in Response to salicylate and other Compounds in Escherichia coli
(2017-11-28)Cytosolic protein degradation is crucial for cellular homeostasis as it orchestrates protein turnover by destruction of misfolded, unstable and abnormal proteins. This process has two main stages: (i) an ATP-dependent stage ... -
The Elucidation of the Mechanism of Meiotic Chromosome Synapsis in Saccharomyces Cerevisiae : Insights into the Function of Synaptonemal Complex, Hop1 and Red1, Proteins and the Significance of DNA Quadruplex Structures
(2017-12-03)Meiosis is a specialized type of cell division where two rounds of chromosome segregation follow a single round of DNA duplication resulting in the formation of four haploid daughter cells. Once the DNA replication is ... -
Elucidation of the Role of Nse1, a RING Domain Containing Component of Smc5/6 complex, in Maintenance of Chromosome Stability in Saccharomyces cerevisiae
(2018-05-21)Structural Maintenance of Chromosomes (SMC) proteins are a highly conserved class of proteins required for the maintenance of genome stability and regulate nearly all aspects of chromosome biology. Eukaryotes, such as the ... -
Endotoxin Peptide/Protein Interactions: Thermodynamic And Kinetic Analysis
(Indian Institute of Science, 2006-05-15)Endotoxin or Lipopolysaccharide (LPS) is the invariant structural component of gram negative bacterial outer membranes and is the chief causative factor of Sepsis or endotoxic shock. Sepsis is a syndrome that has very high ... -
Evaluation of Alternate DNA Structures at c-MYC Fragile Region Associated with t(8;14) Translocation And Role of GNG Motifs During G-quadruplex Formation
(2017-10-11)Watson-Crick paired B-form DNA is the genetic material in most of the biological systems. Integrity of DNA is of utmost importance for the normal functioning of any organism. Various environmental factors, chemicals and ... -
Expanding The Horizon Of Mycobacterial Stress Response : Discovery Of A Second (P)PPGPP Synthetase In Mycobacterium Smegmatis
(2015-12-21)The stringent response is a highly conserved physiological response mounted by bacteria under stress (Ojha and Chatterji, 2001; Magnusson et al., 2005; Srivatsan and Wang, 2007; Potrykus and Cashel, 2008). Until recently, ... -
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. ... -
Exploring the Roles of Phase Variable HpyAII Restriction-modification System in the Human Pathogen Helicobacter pylori
Helicobacter pylori is a Gram-negative microaerophilic bacteria known to infect as much as 80% of some populations with an average morbidity range of around 50% of the world population. It has been recognized as a definitive ... -
Functional Role Of Heat Shock Protein 90 From Plasmodium Falciparum
(2009-03-18)Molecular chaperones have emerged in recent years as major players in many aspects of cell biology. Molecular chaperones are also known as heat shock proteins (HSPs) since many were originally discovered due to their increased ... -
Functionally Interacting Proteins : Analyses And Prediction
(2016-05-04)Functional interaction of proteins is a broad term encompassing many different types of associations that are observed amongst proteins. It includes direct non-covalent interactions where the interacting proteins physically ...
