Characterization of the transsulfuration enzyme Cystathionine beta-synthase as a novel regulatory node in the sulfur metabolism of Mycobacterium tuberculosis
Methionine and cysteine metabolisms are important for the survival and pathogenesis of Mycobacterium tuberculosis (Mtb). The transsulfuration pathway converts methionine to cysteine and represents an important link between ...
Immunological consequences of host signaling-regulated epigenetic modification(s) during mycobacterial pathogenesis
Introduction: Mycobacterium tuberculosis (Mtb), the principal etiological agent of pulmonary tuberculosis (TB), continues to co-evolve with the human population making itself one of the most potent infectious killer in the ...
Manipulating Bacterial and Host Reactive Oxygen Species (ROS)- based mechanisms to potentiate killing of Mycobacterium tuberculosis (Mtb)
Mycobacterium tuberculosis (Mtb) is evolutionarily equipped to resist exogenous reactive oxygen species but shows vulnerability to an increase in endogenous ROS (eROS). Since eROS is an unavoidable consequence of aerobic ...
Biochemical and functional characterisation of cyclic AMP-binding, universal stress proteins from mycobacteria
The genus Mycobacterium harbours several pathogenic species, including M. tuberculosis, the causative agent of tuberculosis, which alone is responsible for nearly 1.3 million deaths globally every year. Understanding the ...
Influence of the substrate specificity of Mycobacterium tuberculosis ClpX on the transcriptional profile
Cellular homeostasis in bacteria is maintained by diverse molecular machines. These include several one-component systems (OCS), two- component systems (TCS), chaperone proteins, proteases, proteolytic complexes and ...
Biochemical and Functional Characterization of the Mycobacterial PdtaS-PdtaR Two Component System
Two-Component Systems (TCSs) are primarily prokaryotic modes of cell signaling involving a receptor sensor kinase (SK) that senses stimuli and a response regulator (RR) that effects a response, usually at the level of ...
Ageing associated altered host response to bacterial infection
Chapters in which I have elucidated and elaborately described how senescence alters the cellular response to infection, here I demonstrate how senescence in multiple tissues simultaneously contribute to pathogen spread and ...
Post translational modification and DNA binding studies with two nucleoid associated proteins of Mycobacterium tuberculosis
Genome in prokaryotes is found in a small confinement called nucleoid. The nucleoid compaction is brought about by the combined action of topoisomerases and Nucleoid associated proteins (NAPs). Topoisomerases maintain ...
Malat1 and COP1 mediated host responses orchestrate mycobacterial pathogenesis
Tuberculosis, which is caused by Mycobacterium tuberculosis (Mtb), is viewed to be the predominant cause of death arising due to bacterial infection. Further, the emergence of MDR/XDR strains and co-infections has compounded ...
Heterogeneous host-pathogen interactions contribute to antibiotic tolerance in Mycobacterium tuberculosis
Eradication of Mycobacterium tuberculosis (Mtb) requires strategies targeting bacteria inside the host. Mtb exhibits heterogeneity in redox metabolism inside macrophages to evade killing by anti-TB drugs. If and how ...
