Characterization Of HP1369-HP1370 From Helicobacter Pylori : A Novel ε Type N6 –Adenine Methyltransferase
(2013-07-18)Helicobacter pylori is one of the most genetically diverse bacterial species that successfully colonizes at least 50% of the world population. It has been associated with humans for thousands of years and most probably ... -
Characterization of mouse Apolipoprotein L9 and investigation of its cellular functions
This thesis is divided into 3 chapters. Chapter 1, titled General Introduction, is a chapter that familiarizes the reader with the general subject matter of the thesis so that the content of Chapters 2 and 3 can ... -
Characterization Of Structural And Non-structural Proteins Of Positive Sense, Single-stranded RNA Plant Viruses
(2015-07-08)In the present thesis, two positive sense single-stranded RNA viruses have been used as models to understand the structure and function of viral-encoded proteins. One of them, Pepper Vein Banding Virus (PVBV; genus Potyvirus; ... -
Characterization of Thymocyte Subpopulations and Mechanistic Insights during Various Modes of Thymic Atrophy
T lymphocytes along with B lymphocytes constitute the adaptive immune system, which is critical for host defence. The progenitors of T cells arise in the bone marrow and the sequential development of T cells occurs in the ... -
Chimeric Virus Like Particles as Nanocarriers for Antibody Delivery in Mammalian Cells & Role of Groundnut Bud Necrosis Virus NSs in Viral Life Cycle
(2018-08-02)Knowledge of the dissociation constants of the ionizable protons of weak acids in aqueous media is of fundamental importance in many areas of chemistry and biochemistry. The pKa value, or equilibrium dissociation constant, ... -
Cloning and Expression of a Diagnostic Antigen for Invasive Amoebiasis
(Indian Institute of Science, 2005-04-29)A crude extract of axenically grown amoebae was used as antigen in order to develop an AB microELISA for the detection and quantitation of E. histolytica-specific IgG antibodies. This ELISA was used to screen individual ... -
Comparative evaluation of retrograde regulatory proteins (Rtg1p, Rtg2p, and Rtg3p) of Saccharomyces cerevisiae and Pichia pastoris and identification of P. pastoris RtgXp as a novel regulator of multiple metabolic pathways
Our work demonstrates for the first time that PpRtgXp, a basic, helix-loop-helix (bHLH) protein, is a global regulator of carbon metabolism. PpRtgXp constitutively localizes inside the nucleus. Despite lacking the C-terminal ... -
A Comparative Study On The Sensitivity Of Cells Of Different Lineages To Plant Ribosome Inactivating Protein - Abrin
(2010-12-08)Proteins with selective toxicity have been investigated for use in many ways. One class of proteins, ribosome-inactivating proteins (RIPs), is found throughout the plant kingdom as well as in lower organisms like certain ... -
Computational and Experimental Approaches to Protein Design
Protein design is a rapidly maturing field, with the goal of designing proteins with customized structures and functions. A large number of protein structures are experimentally determined, which have facilitated an ... -
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 ... -
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 ... -
Cytotoxic T lymphocyte Responses Against Japanese Encephalitis Virus In Mice: Specificity And Immunotherapeutic Value
(Indian Institute of Science, 2005-10-07)Cytotoxic T Lymphocytes (CTL) are known to play an important role in clearing infectious virus from infected hosts in a variety of viral infections. Depending on the type of virus and mode of virus entry both class I and ... -
Deciphering the biochemical and biophysical properties of the Holliday junction resolvases RuvC and RuvX from Mycobacterium smegmatis
Homologous recombination (HR) is a ubiquitous cellular process that occurs in all three domains of life as well as in DNA and RNA viruses. In eukaryotes, HR is critically important for homology-directed DNA repair (HDDR) ... -
Determination of significance of SUMOylation of the Smc5/6 complex
The fascination of scientists to the Smc5/6 complex began in the 1990s, with the characterization of UV and γ radiation-sensitive rad18 mutant and its identification as a component of a novel Structural Maintenance of ... -
Development and Characterization of a potent Tumor Necrosis Factor-alpha blocking agent
Tumor necrosis factor-α (TNFα), one of the major pro-inflammatory cytokines, plays a pivotal role in an effective inflammation process and immune response. TNFα interacts with two different receptors, TNFR1 and TNFR2, which ... -
Developmental And Functional Regulation Of DNA Topoisomerase II in Postnatal Rat Testis
(Indian Institute of Science, 2005-11-23)Characterization of the polyoma virus chromosome as a circular, double-stranded, supercoiled DNA (Weil and Vinograd, 1963; Vinograd et al.,-1965) made it apparent that the DNA enzymatic machinery faces a formidable problem ... -
