Biochemical Characterization Of An Acid-Adaptive Type III DNA Methyltransferase From Helicobacter Pylori 26695 And Its Biological Significance
(2014-12-15)Enzyme DNA methylation is an important biochemical process that imprints DNA with additional information. DNA methylation is catalyzed by S-adenosyl-L-methionine (AdoMet)-dependent methyltraferases (MTases). Prokaryotic ... -
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 ... -
Delineation Of Signal Transduction Events During The Induction Of SOCS3 By Mycobacterium Bovis BCG : Possible Implications For Immune Subversion Mechanisms
(2010-09-30)Pathogenic Mycobacteria are among the most unrelenting pathogens known to mankind as one-third of the world population is latently infected with Mycobacterium tuberculosis, the causative agent of pulmonary tuberculosis. ... -
Delineation Of Signaling Events Regulating Mycobacterium Bovis BCG Induced Expression Of MMR-9 And SPI6 : Possible Implications For Immune Subversion Mechanisms
(2013-08-30)One key to the pathogenic potential of the mycobacteria lies in their capacity to resist destruction by infected macrophages and dendritic cells. Robust host immune responses during mycobacterial infection often involve a ... -
Elucidating the Role of MsRbpA in Rifampicin Tolerance and Transcription Regulation of Mycobacterium Smegmatis
(2018-04-12)RNA polymerase binding protein A (RbpA) was first discovered as a RNA polymerase binding protein from Streptomyces. coelicolor. It was shown to cause rifampicin tolerance to RNA polymerase in vitro and leads to basal level ... -
Helicobacter Pylori Restriction-Modification Systems : Possible Roles Beyond Genome Protection
(2013-06-06)Helicobacter pylori is one of the most potential and successful human pathogen which colonizes atleast 50% of world population. One of the important characteristics of this pathogen is the degree of allelic diversity and ... -
Insights into Occurrence and Divergence of Intrinsic Terminators and Studies on Rho-Dependent Termination in Mycobacterium Tuberculosis
(2018-04-11)Two mechanisms, intrinsic and factor-dependent, have evolved for accomplishing the termination of transcription in eubacteria. In this thesis, the first chapter is an introduction to the topic that presents what is known ... -
Investigations on the Possible Role of Aromatic β-Glucoside Metabolism in Self-Defense in Enterobacteriaceae
(2018-04-02)Bacteria are ubiquitous in all ecosystems and are often challenged by multiple stresses such as extreme temperatures, high salt concentrations, nutrient limitation, pH variations, radiation, predation and the presence of ... -
Investigations On The Role Of The Global Regulator H-NS In The Survival Of Escherichia Coli In Stationary-Phase
(2015-08-17)Studies on stationary phase cultures of microorganisms in the laboratory have helped us understand the genetic and physiological basis of adaptation in their natural habitats. Stasis or decline in bacterial populations due ... -
Mechanistic And Functional Insights Into Mycobacterium Bovis BCG Induced Expression Of Cyclooxygenase-2 : Implications For Immune Evasion Strategies
(2014-09-25)Mycobacteria are multifaceted pathogens capable of causing both acute disease as well as an asymptomatic latent infection. Protective immunity against pathogenic mycobacteria depends principally on cell-mediated immunity ... -
Mechanistic And Functional Insights Into Mycobacterium Bovis BCG Triggered TLR2 Signaling : Implications For Immune Evasion Strategies
(2015-09-04)Mycobacteria are multifaceted pathogens capable of causing both acute disease as well as an asymptomatic latent infection. Host immune responses during mycobacterial infection involve potent cell effector functions including ... -
Metallophosphoesterases In Mycobacteria Enigmatic Roles In Regulating Mycobacterial Physiology
(2014-04-29)Pathogenic bacteria such as M.tuberculosis have evolved several mechanisms to aid their intracellular survival and subvert host defenses. One of the contributing factors is thought to be the production and secretion of ... -
Moonlighting Functions of the Rv0805 Phosphodiesterase from Mycobacterium Tuberculosis
(2018-04-18)All organisms must sense and respond to their environment in order to survive. The processes that allow a living cell to sense changes in its environment, and respond appropriately are collectively referred to as ‘signal ... -
Stringent Response In Mycobacteria: Molecular Dissection Of Rel
(2007-11-29)Adaptation to any undesirable change in the environment dictates the survivability of many microorganisms. Such changes generate a quick and suitable response, which guides the physiology of bacteria. Stringent response ... -
Structural And Biophysical Analysis Of The Regulatory Mechanism Of Mycobacterium Tuberculosis Sigma Factors
(2010-12-07)Mycobacterium tuberculosis has one ribosomal RNA operon. The survival of this bacillus thus depends on a transcription mechanism that can effectively couple gene expression to changes in the environment. σ factors are ... -
