Protein NMR Studies of E. Coli IlvN and the Protease-VPg Polyprotein from Sesbania Mosaic Virus
(2018-04-03)Acetohydroxyacid synthase is a multisubunit enzyme that catalyses the first committed step in the biosynthesis of the branched chain amino acids viz., valine, leucine and isoleucine. In order to understand the structural ... -
Proteomic Approaches to Study Glioma Development, Progression and Therapy
(2018-04-02)Astrocytoma, the tumor of astrocytic origin, accounts for about 60 % of the primary brain tumors. As per World Health Organization grading system, astrocytoma is classified as circumscribed astrocytoma (Grade I; pilocytic ... -
Regulation of Chitin Oligosaccharides Utilization in Escherichia Coli
(2018-04-11)The genome of Escherichia coli harbors several catabolic operons involved in the utilization of a wide variety of natural compounds as carbon sources. The chitobiose (chu) operons of E.coli Is involved in the utilization ... -
Role of DNA Methylation in Glioblastoma Development
(2018-04-11)Glioblastoma (GBM) is the most common and malignant of the glial tumors. These tumors may develop from lower-grade astrocytomas (diffuse astrocytoma; grade II or anaplastic astrocytoma; grade III) through a progressive ... -
Role of Grp 75 Chaperone Folding Machinery in the Maintenance of Mitochondrial Protien Quality Control
(2018-04-03)My research focuses on understanding the importance of human mitochondrial Hsp70 (Grp75) chaperone machinery for the maintenance of protein quality control inside the mitochondrial matrix. The investigations carried out ... -
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 Studies on Mycobacterial Aspartic Proteinases and Adenylyl Cyclases
(2018-04-11)Structural investigations on two mycobacterial enzymes were carried out. Tuberculosis still remains a major threat to mankind even though drugs against it have been in use for many decades. The emergence of drug resistant ... -
Structural Studies on Mycobacterium Tuberculosis Peptidyl-tRNA Hydrolase and Ribosome Recycling Factor, Two Proteins Involved in Translation
(2017-11-27)Protein synthesis is a process by which organisms manufacture their proteins that perform various cellular activities either alone or in combination with other similar or different molecules. In eubacteria, protein synthesis ... -
Structure, Stability and Evolution of Multi-Domain Proteins
(2018-04-11)Analyses of protein sequences from diverse genomes have revealed the ubiquitous nature of multi-domain proteins. They form up to 70% of proteomes of most eukaryotic organisms. Yet, our understanding of protein structure, ... -
Studies on Novel Functional Responses of Mouse Peritoneal Macrophages to Interferon-gamma : Roles of Nitric Oxide Synthase 2
(2018-04-18)Interferons are known cytokines that display antiviral, anti-proliferative and immuno-modulatory functions in the host. Interferon-gamma (Ifnγ) is the only type II family interferon that binds to the heterodimeric receptor ... -
Study Of Rpb4, A Component Of RNA Polymerase II As A Coordinator Of Transcription Initiation And Elongation In S. Cerevisiae
(2017-05-24)RNA polymerase II (Pol II) is the enzyme responsible for the synthesis of all mRNAs in eukaryotic cells. As the central component of the eukaryotic transcription machinery, Pol II is the final target of transcription ... -
Target Genes and Pathways Regulated by OsMADSI during Rice Floret Specification and Development
(2018-04-12)In angiosperms, specialized reproductive structures are borne in flowers to ensure their reproductive success. After the vegetative growth, plants undergo reproductive phase change to produce flowers. Floral meristems (FMs) ... -
Transcriptional and Posttranscriptional Regulation of the Tumor Suppressor CDC73 in Oral Squamous Cell Carcinoma : Implications for Cancer Therapeutics
(2018-04-16)CDC73, also known as HRPT2, is a tumour suppressor gene whose expression is lost or downregulated in parathyroid, renal, breast, uterine and gastric cancers. However, the reports regarding the role of CDC73 in oral squamous ... -
Ultrastructural and Molecular Analyses of the Unique Features of Cell Division in Mycobacterium Tuberculosis and Mycobacterium Smegmatis
(2018-04-13)The Mycobacterium genus contains major human pathogens, like Mycobacterium tuberculosis and Mycobacterium leprae, which are the causative agents of Tuberculosis and Leprosy, respectively. They have evolved as successful ... -
Understanding the Regulatory Steps that Govern the Activation of Mycobacterium Tuberculosis σK
(2018-07-28)A distinctive feature of host-pathogen interactions in the case of Mycobacterium tuberculosis is the asymptomatic latent phase of infection. The ability of the bacillus to survive for extended periods of time in the host ... -
Unfolding the Mechanism of Notch1 Receptor Activation : Implications in Cancer Stem Cell Targeting
(2018-05-01)Notch receptors and ligands are single-pass transmembrane proteins which play important roles in cell-cell communication. Notch in ‘harmony’ with other signaling pathways regulate the entire diversity of metazoan life ... -
