Engineering Reverse Turns: Implications in Conformation, Stability and Bioactivity of Peptides and Proteins
The work presented in this thesis provides an overview of the potential role of N-methylation in inducing reverse turns. Backbone N-methylation is one of the common modifications designed by nature and exploited by humans ... -
Probing the Splicing and Enzymatic Function of Fission Yeast Prp16 – A DEAD Box RNA Helicase
Nuclear pre-mRNA splicing occurs at precisely conserved sequence elements at and around the splice sites which result in ligation of exons and release of intron as lariat. The Schizosaccharomyces pombe genome is an apt ... -
Is Spatial Map Shaped by Environmental Determinants?
Humans and other animals form internal mental maps of the outer world in order to navigate. Hippocampal place cells and grid cells in MEC (medial entorhinal cortex) are the key components of this navigation system. However, ... -
Understanding Rules of Assembly and Species Interactions in Mixed-species Bird Flocks
In mixed-species bird flocks (flocks hereafter), participants vary in their degree of similarity with each other. Flock participants can gain group size (supplementary) benefits by choosing similar flock partners, or ... -
Multimodal Duetting and Pair Formation in a Paleotropical False Leaf Katydid, Onomarchus uninotatus
The spectacular diversity in the pair-formation strategies among animal groups has attracted the attention of many over the years. The roots of this diversity lie in the diversity of challenges that males and females face ... -
Foraging Decisions of the Lesser False Vampire Bat, Megaderma Spasma in a Heterogeneous Landscape
Predators make various foraging decisions at different spatial and temporal scales. Such decisions can be studied at two levels: patch decisions at the landscape level, and prey decisions at the foraging patch level. In ... -
Immune-metabolic response of Caenorhabditis elegans to Enterococcus faecalis
Immune response to pathogens is energetically expensive to the host. In this study, we show that Caenorhabditis elegans exposed for 8 hours to pathogenic Gram-positive bacteria, Enterococcus faecalis and Staphylococcus ... -
The Influence of Glycerol and Specific Genes on the Asymmetric Cell Division in Mycobacteria
The Influence of Glycerol and Specific Genes on the Asymmetric Cell Division in Mycobacteria Submitted by Atul Pradhan (S.R. No. 03-04-00-10-11-14-1-11678) Background Information: Mycobacteria maintain heterogeneity in ... -
Structural and related studies on Mycobacterium tuberculosis pantothenate kinase
Pantothenate kinase (PanK) is a ubiquitous and essential enzyme that catalyses the first step in the universal Coenzyme A (CoA) biosynthetic pathway. In this step pantothenate is converted to phosphopantothentate, which ... -
Development and application of sequence-based approaches for recognition and functional characterization of protein kinases
Protein kinases, the third most populous protein family, are a major class of enzymes that regulate a wide range of cellular processes by phosphorylating multiple cellular proteins. There are many conserved sequence motifs ... -
Insight into luteolytic effects of repeated administration of LH in pregnant rats: Analysis of cAMP/PKA pathway during LH-induced luteolysis
The Corpus luteum (CL) is a dynamic endocrine structure that develops in the ovary from the remnants of the ovulated follicle and plays a critical role in the control of estrous/menstrual cycle as well as in establishment ... -
Structural and Functional Characterization of Quadruplex DNA Structures in Human Acetyl-CoA Carboxylase 1 Gene Promoters and Stabilization of G-quadruplex DNA by Carbazole-benzimidazole Conjugates
A number of studies have established that DNA targeting is a successful strategy in anticancer therapy. In recent years, however, the focus has shifted from double-stranded DNA to alternative DNA motifs such as G-quadruplex ... -
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, ... -
Panoramic View of RNA Binding Proteins (RBPs) in Glioblastoma : IMP3, an RBP, is Essential for Glioma Stem-like Cell Maintenance
Gliomas are primary brain tumors in adults that are believed to originate from different types of glial cells. Central nervous system gliomas pose particularly difficult problems because of their tendency towards malignancy, ... -
Systematics and Comparative Biogeography of Vine Snakes (Genus: Ahaetulla, Family: Colubridae) and Pit vipers (Genus: Trimeresurus, Family: Viperidae) in Peninsular India
The Indian subcontinent is a considered a mega biodiverse region with representative regions belonging to three of the 35 global biodiversity hotspots, including the Western Ghats in Peninsular India and the Eastern ... -
Identification and Characterisation of a miRNA releasing activity from Caenorhabditis elegans
MicroRNAs (miRNA) are endogenous, small non coding RNAs, which play a prominent role in eukaryotic gene regulation. Perturbations leading to an altered abundance of miRNAs can lead to pathological conditions like neurological ... -
Understanding the redox homeostatic mechanisms in Mycobacterium tuberculosis infection
Mycobacterium tuberculosis (Mtb) is an obligate intra-cellular pathogen that causes the disease tuberculosis (TB) in its human hosts. An estimated 1% of the world population is reported to get infected with the disease ... -
Dissecting the Role of Calcium Binding Proteins in Muscle using Drosophila Indirect Flight Muscles as the Model System
Muscle development and function are highly synchronized processes that involve simultaneous action of several transcription factors, signalling cascades, kinases and phosphatases, ion channels, structural proteins and ... -
Insights into Differentiation of Pluripotent Stem Cells to Cardiac Progenitors and Cardiomyocytes
The mammalian heart is the first organ formed during development. It forms the crux of the circulatory system of the body and pumps blood (and therefore, nutrients) to all parts of the body. The continuous functioning of ... -
Genetic control of Embryonic and Adult muscle development in Drosophila melanogaster by Mlp60A
Many genetic regulatory networks are required to define the overall characters in a living organism. Characters which are necessary for survival in the wild are often canalized, such that despite genetic and environmental ...
