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, ...
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 ...
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 ...
Non-repetitive Structures In Proteins : Effects Of Side-chain And Solvent Interactions With The Backbone
(Indian Institute of Science, 2006-05-12)
The work presented in this thesis deals with the analysis of protein crystal structures with an emphasis on the stereochemical aspects of the folded conformation of proteins. The various analyses described have been performed ...
Starvation Response In Mycobacterium Smegmatis : A Tale Of Two Proteins
(2010-10-19)
The Dps (DNA-Binding Protein from Starved Cells) proteins are a class of stress-specific proteins with a major role in protecting DNA during the stationary phase of bacterial growth, through direct physical binding as well ...
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 ...
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 ...
Energetics Of Protein-Carbohydrate Recognition
(Indian Institute of Science, 2006-04-28)
The work embodied in this thesis pertains to an attempt to understand better, the molecular basis of protein-carbohydrate recognition. For this purpose a systematic study was undertaken, not only of the energetics of ...
