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 ...
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 ...
Nucleoid-associated Proteins of Mycobacterium tuberculosis : Insights into their Functions
Bacteria face the challenging task of compacting their chromosomes to accommodate them in a small cytoplasmic volume and at the same time maintaining the nucleoids in a highly organized and dynamic state for transcription, ...
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 ...
Regulation of Host Innate Immune Responses by Hippo Signaling Pathway during Pattern Recognition Receptors (PRRs) Driven Inflammation : Implication for Host-Pathogen Interactions
Innate immunity refers to the first line of defence system of the host that comes into play immediately or within hours of appearance of invading pathogens like bacteria, viruses and fungi. Cells of the innate immune system ...
Wnt/β-Catenin-dependent Epigenetic Factors Shape Host Immune Responses During Mycobacterial Infection
The genus mycobacterium has more than 120 species of bacteria; one being M. tuberculosis (Mtb), the etiological agent of tuberculosis (TB). During infection, the host mounts a heightened immune response to contain the ...
Topoisomerase i from mycobacterium tuberculosis : Dynamics of enzyme function and inhibitor development
Inside the bacterial cell, the genetic material is maintained in a negatively supercoiled state within a compact space. The supercoiling of the genome undergoes topological perturbations during a variety of cellular processes ...
Insights into the Regulation of Transcription Initiation of DNA Gyrase and Role of Transcription Factor Gre from Mycobacterium tuberculosis
Genus Mycobacterium comprises a large number of species including many pathogens such as Mycobacterium leprae, Mycobacterium abscessus and Mycobacterium tuberculosis (Mtb), the last one is the causative agent of the fatal ...
