Development And Applications Of Computational Methods To Aid Recognition Of Protein Functions And Interactions
(2011-10-03)Protein homology detection has played a central role in the understanding of evolution of protein structures, functions and interactions. Many of the developments in protein bioinformatics can be traced back to an initial ... -
Structural Studies Of Mycobacterial Uracil-DNA Glycosylase (Ung) And Single-Stranded DNA Binding Protein (SSB)
(2011-09-21)For survival and successful propagation, every organism has to maintain the genomic integrity of the cell. The information content, in the form of nucleotide bases, is constantly threatened by endogenous agents and ... -
Structural Studies On Mycobacterium Tuberculosis Pantothenate Kinase (PanK)
(2011-07-18)Pantothenate kinase (PanK) is an ubiquitous and essential enzyme that catalyzes the first step in the universal Coenzyme (CoA) biosynthesis pathway. In this step, pantothenate (Vitamin B5) is converted to 4′-phosphopantothenate, ... -
Intrinsic Versus Induced Variations In DNA Structure
(2011-07-18)The binding of different proteins involved in processes such as transcription, replication and chromatin compaction to regions of the genome is regulated by the structure of DNA. Thus, DNA structure acts as the crucial ... -
Structural And Functional Studies On Staphylococcus Aureus Enzymes Involved In L-Lysine Biosynthesis
(2011-05-24)Proteins associated with metabolic pathways have received considerable attention in an effort to understand the molecular details of the complex reactions catalyzed in vivo. Enzymes belonging to these pathways have also ... -
Studies On Sesbania Mosaic Virus Asssembly And Structure And Function Of A Survival Protein (SurE) From Salmonella Typhimurium
(2011-03-29)X-ray crystallography is a powerful method for determining the three-dimensional structures of biological macromolecules at atomic resolution. Crystallography can reliably provide the answer to many structure related ... -
Solution Structural Studies And Substrate Binding Properties Of The Amino-Terminal Domain Of E.coli Pantothenate Synthetase
(2011-03-29)Pantothenate synthetase (PS), which catalyzes the last step in the pantothenate (vitamin B5) biosynthesis, is a dimeric enzyme present in bacteria, fungi and plants. The enzymatic properties of PS from Escherichia Coli, ... -
Biophysical Studies On The Plastic And Cooperative Properties Of Single Voltage Gated Na+ And Leak K+ Ion Channels
(2011-03-08)Ion channels are fundamental molecules in the nervous system that catalyze the flux of ions across the cell membrane. There are mounting evidences suggesting that the kinetic properties of ion channels undergo activity-dependent ... -
Determinants Of Globular Protein Stability And Temperature Sensitivity Inferred From Saturation Mutagenesis Of CcdB
(2011-02-25)The unique native structure is a basic requirement for normal functioning of most proteins. Many diseases stem from mutations in proteins that destabilize the protein structure thereby resulting in impairment or loss of ... -
Newer Insights On Structure, Function And Regulation Of Dps Protein From Mycobacterium smegmatis
(2010-12-29)The first chapter will provide an introduction to the physiology, pathogenesis and biology of mycobacteria. Host-pathogen interactions, different modes of resistance of the bacteria, adaptations for survival under nutrient ... -
Structural And Functional Analysis Of Proteins With The Double Stranded β-helix (Cupin) Domains
(2010-12-24)Proteins performing catalytic roles predominantly occur in a few protein folds. Functional diversity within a common structural scaffold has been attributed to conformational features that enable exploration of reaction ... -
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 ... -
Structural Studies On Mycobacterial RecA And RuvA
(2010-10-21)Homologous recombination is a fundamental cellular process evolved to maintain genomic integrity and to generate genetic diversity. It plays a crucial role in DNA repair, correct segregation of meiotic chromosomes and ...
