Cell Survival Strategies : Role Of Gyrase Modulatory Proteins
(2010-07-21)A steady state level of negative supercoiling is essential for chromosome condensation, initiation of replication and subsequent elongation step. DNA gyrase, found in every eubacteria, serves the essential housekeeping ... -
DNA Gyrase And Topo NM From Mycobacteria : Insights into Mechanism And Drug Action
(2017-10-26)Maintenance of a topological homeostasis by introduction and removal of the supercoils to relieve excessive strain on the DNA is a hallmark of topoisomerase function in the cell. The requirement of the topoisomerases during ... -
How Much Initiator tRNA Does Escherichia Coli Need?
(2017-11-27)The work discussed in this thesis deals with the significance of initiator tRNA gene copy number in Escherichia coli. A summary of the relevant literature discussing the process of protein synthesis, ... -
Influence Of FtsH Protease On The Medial FtsZ Ring In Escherichia Coli
(2013-07-17)FtsH is an essential AAA family Zn++ metalloprotease of Escherichia coli, possessing ATPase-dependent chaperon activity and ATP-dependent protease activity. Heat shock transcription factor Sigma32, LpxC, SecY, and bacteriophage ... -
Mechanism Of Activation Of Bacteriophage Mu Late Genes By Transcription Activator Protein C
(2013-01-24)Initiation of transcription is a major step in the regulation of gene expression. A dominant theme in regulation of gene expression lies in understanding the mechanism involved in selective expression of the genes in ... -
Molecular Characterisation Of Mycobacterium Tuberculosis Fic Protein And Its Gene And Identification And Characterisation Of A Novel Functional Interaction Between FtsZ And NDK in Mycobacteria
(2016-04-29)Living organisms employ different kinds of mechanisms, to regulate the functions of genes or their products, which may help in maintaining homeostasis inside the cell or may help in fighting hostile environment in the case ... -
Molecular pathways governing maturation and decay of precursor piRNAs in Caenorhabditis elegans
Piwi-interacting RNAs (piRNAs) are an animal-specific class of germline-enriched small non-coding RNAs that play a crucial role in germline development and fertility in diverse organisms. In Caenorhabditis elegans (C. ... -
Regulation and Characterization of Transcription Factor Activator Protein-2 Alpha (AP-2α)
(2018-02-11)Introduction AP2α is a 52 kDa retinoic acid inducible and developmentally regulated activator of transcription, which binds to the DNA in a sequence-specific manner. Transcription factor AP-2α was isolated from HeLa cells ... -
Structure-Function Correlative Studies On The Biochemical Properties (Polymerisation, GTP binding, GTPase) Of Mycobacterial Cytokinetic Protein FtsZ In Vitro
(2010-03-26)FtsZ, the principal cell-division protein, polymerizes in GTP-dependent manner in vitro (Bramhill and Thompson, 1994; Mukherjee and Lutkenhaus, 1994; Rivas et al., 2000). FtsZ polymerization at the mid-cell site of bacterium ... -
Studies on Interactions between ARE Binding Proteins and Splicing Factors and their Role in Altered Splicing of PDGF-B ORF
(2018-03-03)Pre-mRNA splicing is an important level in posttranscriptional gene regulation that is essential for accurate protein synthesis and generating protein diversity. The abundance of cryptic splice sites and long intronic DNA ... -
Studies On The Mechanism Of Uracil Excision Repair In Escherichia Coli And Structure-Function Relationship Of Single Stranded DNA Binding Proteins From Escherichia Coli And Mycobacterium Tuberculosis
(2014-12-11)To maintain the genomic integrity, cell has evolved various DNA repair pathways. Base Excision Repair pathway (BER) is one such DNA repair pathway which is dedicated to protect DNA from small lesions such as oxidation, ... -
Studies On The Structural And Biological Properties Of Rotavirus Enterotoxigenic Non-structural Protein 4 (NSP4)
(2013-04-01)Rotavirus is the major cause of infantile gastroenteritis. Each year more than 600,000 young children are estimated to die in developing countries throughout the world. Rotavirus infection can be either symptomatic or ... -
Understanding Functions for Fission Yeast Pre-mRNA Splicing Factors SpPrp18 and SpSlu7 in Constitutive and Alternative Splicing
(2017-11-29)Exonic sequences of eukaryotic genes are interspersed with introns which when accurately removed from the primary transcript (pre-mRNA) results in a functional transcript. These splicing reactions are carried out by the ...
