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 ... -
Elucidating the Roles of Lon Protease and its Substrate, MarA, in Response to salicylate and other Compounds in Escherichia coli
(2017-11-28)Cytosolic protein degradation is crucial for cellular homeostasis as it orchestrates protein turnover by destruction of misfolded, unstable and abnormal proteins. This process has two main stages: (i) an ATP-dependent stage ... -
Molecular dissection of Komagataella phaffii Rtg1–RtgX function and development of a glutamate-responsive protein expression platform
In Saccharomyces cerevisiae, the basic helix-loop-helix leucine zipper (bHLH-LZ) proteins Rtg1 and Rtg3 form a heterodimeric transcription factor complex that mediates the retrograde response. In Candida albicans, these ... -
Role of Escherichia coli UvrD helicase in resolving G-quadruplex DNA structures
G-quadruplex (G4) secondary structures have been implicated in various biological processes, including gene expression, DNA replication and telomere maintenance. However, unresolved G4 structures impede replication ... -
Studies on the roles of Lon protease and its substrates during antibiotic resistance in Escherichia coli: modulatory effects of nitroaromatics and nitrofurantoin
Bacteria adapt to environmental stresses, including antibiotic stress, by regulating various genes and metabolic pathways. In prokaryotes, the energy-dependent protein degradation is controlled primarily by two ... -
Understanding the Mechanism of Homologous Recombination in Mycobacterium Tuberculosis : Exploring RecA as an Antibacterial Target and Characterization of Holliday Junction Resolvases
(2018-08-09)Homologous recombination (HR) is conserved across all three domains of life and is associated with a number of key biological processes. Over the years, numerous genetic, biochemical and structural studies have uncovered ...
