Molecular Mechanisms Underlying Phosphatidylinositol-Specific Phospholipase C Mediated Regulation Of Lipid Metabolism
(2016-03-04)Phosphoinositide-specific phospholipase C (PLC) is involved in Ca2+ mediated signalling events that lead to altered cellular status. PLC activation causes hydrolysis of phosphatidylinositol 4,5-bisphosphate (PIP2) and ... -
Molecular pathways governing maturation and decay of precursor piRNAs in Caenorhabditis elegans
Piwi-interacting RNAs (piRNAs) are an animal-specific class of germline-enriched small non-coding RNAs that play a crucial role in germline development and fertility in diverse organisms. In Caenorhabditis elegans (C. ... -
Mxr1p is a Global Regulator of Multiple Metabolic Pathways in the Methylotrophic Yeast Pichia Pastoris
(2018-03-01)The present study is aimed at examining the ability of Pichia pastoris to utilize acetate and amino acids as the sole sources of carbon. We demonstrate that the zinc finger transcription factor Mxr1p, which is a positive ... -
Mycobacterium Smegmatis RecA And SSB : Structure-Function Relationships, Interaction With Cofactors And Accessory Proteins
(2011-04-06)Homologous genetic recombination, because of its fundamental roles in the maintenance of genome stability and evolution, is an essential cellular function common to all organisms. This process also plays important roles ... -
Mycobacterium tuberculosis RecA intein, a novel LAGLIDADG homing endonuclease, displays dual target specificity in the presence of alternative cofactors
(Indian Institute of Science, 2005-05-10)Mobile inteins and introns are genetic elements capable of self-propagation by “homing” into host genes and occur in entire taxonomy: eubacteria, eukarya, archaea and viruses. The process of “homing” is promoted by an ... -
New Anticancer Secondary Metabolites from an Endophytic Fungus Chaetomium Nigricolor Isolated from Catharanthus Roseus : Structural Elucidation and Molecular Mechanism Underlying Anticancer Effects
(2018-06-13)Cancer has become a major health problem due to its high rate of morbidity and mortality. Severe side effects associated with most of the available anticancer drugs and the development of the drug resistant cells are the ... -
Non-repetitive Structures In Proteins : Effects Of Side-chain And Solvent Interactions With The Backbone
(Indian Institute of Science, 2006-05-12)The work presented in this thesis deals with the analysis of protein crystal structures with an emphasis on the stereochemical aspects of the folded conformation of proteins. The various analyses described have been performed ... -

Nucleic Acid-binding Adenylyl Cyclases in Mycobacteria : Studies on Evolutionary & Biochemical Aspects
(2018-02-08)Mycobacterium tuberculosis is one of the most successful human pathogens, estimated to have infected close to one-third of the global human population. In order to survive within its host, M. tuberculosis utilises multiple ... -
Oleosin, a Bifunctional Enzyme is Phosphoregulated by a Protein Kinase
In eukaryotic cells, lipids are indispensable principal components that vitiate biological life. Lipids are classified into two major groups, polar and non-polar lipids. Polar lipids are phospholipids, whereas non-polar ... -
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. ... -
Oxidative Stress In The Brain: Effects Of Hydroperoxides And Nitric Oxide On Glyceraldehyde 3-Phosphate Dehydrogenase And Phosphoinositide Cycle Enzymes
(Indian Institute of Science, 2005-09-01)In the aerobic cell, oxygen can be converted into a series of reactive metabolites, together called as "reactive oxygen species" (ROS). This large group include both radical and non-radical species such as superoxide anion ... -
Peptidase N, A Major Aminopeptidase Belonging To The M1 Family : Biochemical And Functional Implications
(2009-08-05)Intracellular protein degradation is required for maintaining the cellular proteome and regulating cellular processes. This pathway involves proximal ATP-dependent proteases that unfold and translocate proteins targeted ... -
Physiological And Exogenous Means of Regulating DNA Damage Response : Insights into Mechanisms of DNA Repair And Genomic Instability
(2017-09-23)Maintenance of genomic integrity with high fidelity is of prime importance to any organism. An insult which may result in compromised genome integrity is prevented or its consequences are monitored by advanced cellular ... -
