Structural and Functional Analysis of Proteins involved in Microbial Stress Tolerance and Virulence
(2018-08-11)The genus Salmonella consists of pathogenic gram negative organisms which infect intestines of birds, animals and humans. They are the causative agents of salmonellosis which is characterised by diarrhoea, nausea, fever ... -
Structural and Functional Studies on Pyridoxal 5′-Phosphate Dependent Lyases and Aminotransferases
(2017-11-30)The thesis describes structural and functional studies of two PLP-dependent enzymes, diaminopropionate (DAP) ammonia lyase (DAPAL) and N-acetylornithine aminotransferase (AcOAT). The main objective of this work was to ... -
Structural and Functional Studies on Pyridoxal Kinase and Pyridoxal 5′-phosphate Dependent Enzymes
(2018-07-04)Most of the chemical reactions of living cells are catalyzed by protein enzymes. These enzymes are very efficient and display a high degree of specificity with respect to the reaction catalyzed. Cellular activities depend ... -
Structural and Functional Studies on Salmonella typhimurium Propionate Kinase and Photorhabdus luminescens Oxalate Decarboxylase
Acetate and propionate are low molecular mass carbon compounds found abundantly in the soil. Although these compounds have been extensively used as food preservatives because of their ability to inhibit microbial growth, ... -
Structural and Related Studies on Mycobacterial RecA and LexA
(2018-06-18)Genetic material of bacteria is subject to damage due to multitudinous factors, both extrinsic and intrinsic in origin. Mechanisms for the maintenance of genomic integrity are thus essential for a bacterium to survive. ... -
Structural Studies on Bacterial Adenylosuccinate Lyase and Sesbania Mosaic Virus Protease
(2018-05-08)The three-dimensional structures of biological macromolecules and molecular assemblies are becoming increasingly important with the changing methodologies of drug discovery. The structures aid in understanding of protein ... -
